Hello Folks! Welcome to Our Blog.

I understand that much easier than looking at two seperate wiring diagrams and trying to mesh them together. The wiring is similar but not identical. Have you ever tried doing a swap with the 03 PCM? It was the last year before the switchover to the ETC computer and the new transmisson control scheme. Thats the only PCM that will shift the autos. Saved to desktop. I would like to be able to plug in some of the engine monitors available out there, but they don't work with OBDI.

I am runnng the Fiero 4 speed manual. I am considering it. Also as far as I know, tuning software vendors are no longer doing any program upgrades for OBD1. I am just now getting to this point. Any suggestions on whether to do the harness before or after the engine is in? Neither running. Both May sell SE. Not true.

Batch fire wasn't used on the 3. Since then all computers used on these engines have employed Sequential fire injection. Also there are many neat new aftermarket gauges and devices that can show live scan data that only work with OBD2 systems.

There are some other minor advantages the OBD2 system has over OBD1 but in reality, there isn't much else that is different. The one big advantage that OBD1 computers have over OBD2 currently is the fact we can emulate, or tune in real-time with the OBD1 computers since they have removable chips. But I am sure in time that this ability will become available for OBD2 computers as well. Also, Dennis, are you aware there were still "older style" PCMs used on Series 2 Supercharged applications, such as those that came in the Impalas and Monte Carlos?

These computers look identical to the later generation PCMs and I believe would have also worked with your transmission. These computers were set up to work with cable-op throttle bodies, just like your 03 unit.If you'd like send me the full size image and I can see about getting it up for availability at the full size copy.

I wish that we had these diagrams here for all model years and engine swaps. It would really simplify the questions. There were a few of these in the past but I think this is better to visualize.

I finished my swap and I thought some one else might be able to benefit from the wiring diagram I made that might make it more simple to do a quick and "easy" swap. Sorry if the image is not as clear, it was a lot bigger but I reduced it to fit on the server.

Mike Gonzalez did a great job with my conversion but I like schematics to see what he did and to help me troubleshoot it if it is ever needed.

Thanks again and please post often. And welcome to the madness. Posts: From: Tucson, AZ. Registered: May Welcome to PFF! Nice schematic.By SleeperIntrigue, April 19, in Powertrain. Hello all. New to the forums here. Also new to W Bodies. Already posted in the introductions area. Ive heard of it being done a couple of times but theres just no information out there. What I am looking for and need help finding is a Pinout diagram for the bulkhead connector on the firewall of my car.

I was hoping somebody here had a wiring diagram or something that can help me out. Thank in advanced everybody! The Intrigue currently has the 3. To my knowledge, it was the only engin offered in this car from on. I thought about it and just wasnt too sure because I know the Intrigue never had the supercharged engine.

I also didn't know if there were any differences for wiring from year to year. But ill definitely keep that in mind. On the supercharge thing you don't really need a factory supercharged harness The only actual difference is the map plug which is easy to swap. Color coded the same and you just have to add a few inches to the wires with the new plug. I myself have an sc swapped 97 Monte and my particular body style Monte never came supercharged. Awesome man! Thats exactly what I needed to know.Typical engine data sensor and control component locations on the GM 3.

Answer: In most cars, the vehicle speed sensor is located in the tail shaft housing of the transmission. This is where the axle comes out on the passenger side of the trans.

On front wheel drive cars. Best viewed from under the car. Where is the map sensor on this GM v6?

The MAP sensor is located in position 7 on the picture above. The MAP sensor is on top with an electrical connector.

The PCV valve is under the sensor. The sensor and the retainer unscrew from the manifold, and the PCV is inside. It is strictly for diesels. Where's the PCV valve located on a supercharged engine? On the supercharged, it is located under a square metal plate, in similar location as EGR valve on the non-supercharged.

See Above. Where is the Ambient Air Temperature sensor located at? That ambient air temp sensor is located on the front core support, in front of the radiator. Left or right side depending on make, model, and year vehicle. On the V6, the camshaft position sensor is located behind the water pump pulley.

If you were to look at the pulley straight on, it is at about the 9 o'clock position. Where is the crank sensor located at.

The temp sensor only gives a reading to the gauge with the key ON, so this is most likely an instrument panel cluster gauges problem. Ok I replaced that temperature sensor in the photo above, and the new one I got had just two terminals, while the old plug has three receptacles.

Sounds like the parts guy gave you the wrong sensor. Some cars have 1 for the gauge or light, and another for the computer. Where are the air bag sensor location s?Actual product may vary.

Our stock harnesses are 4 feet from the rear of engine passenger side. An engine management harness is pretty much what you will find from most wiring harness companies. Basically, it contains all of the necessary functions to make the engine start and run, while also supplying any necessary signals from the computer such as speedometer and tachometer.

There are no main power feeds required for this harness, just a single switched ignition power will switch a relay in the harness that in turn, supplies 12V power to all of the required engine sensors and the ECU.

These harnesses are designed for the hot rod, or project car that will be using aftermarket or mechanical gauges. There is no output wire for oil pressure or temperature gauges since the aftermarket usually supplies sending units and wiring for these. All of our harnesses, whether it is a complete custom harness, or our engine management harness, come with an easily accessible DLC Data Link Connector that is usually long enough to be mounted in the passenger compartment.

This allows for easy access to the ECU via a laptop or standard scan tool. Harnesses come covered in standard OE split loom. Optional braided loom available for an extra charge. All of the fuses and relays are labeled on the underside of the covers just like a factory vehicle. You can look for a few things to indicate if you have VVT. A non-VVT engine will have 3 wires. This should be noticeable from the back of the engine.

You must be logged in to post a review. Front timing cover with 5 wire connector for VVT, and bulge in the timing cover under the water pump are indications that the engine you are working with has VVT. Reviews There are no reviews yet.

VY L67 wiring loom in a VS. Thread starter benvz Start date Jun 26, With the wiring loom, does it run into the cab or just around the engine bay? I have never done an engine conversion before.

Dual xeon x5690 benchmark

I'm not worried about changing over the engine and transmission, it mainly the wiring loom i'm not sure about. The motor I bought comes with ecu, everything that bolts on, wiring loom, transmission etc.

Any help with installing the wiring loom would be greatly appreciated.

Ok so if no-one can give me any information on those questions, does anyone know if the plugs on the VS are the same as a VY. Seems like a few people have converted there VS V6 to a Supercharged V6 and yet no-one can give me any info on the wiring loom? Your looms are very different, some people modify there VS ecotec looms to suit and have the computer retuned, others source a genuine VS supercharged loom and computer, as far as i know its plug and play if you use a VS super 6 loom, VY loom will not plug straight in, also VT and later super 6's have a boost control solenoid that im pretty sure earlier VS series engine didnt have so theres extra wiring there plus computer inputs ect, you could buy a V6 conversions kit to suit but its probably not worth the effort.

I have already bought the Supercharged V6 and it came with the wiring loom and everything else. So even if I bought a VS L67 wiring loom it would still be no good because of the boost control solenoid? VS instruments are all still independent from computers except the Speedo AFAIK eg, wire runs directly from temp sender to gauge as opposed to - sensor to ecu, to bcm, to gauge. A Vs super 6 loom will work fine, the Boost control solenoid doesnt need to be plugged in, all it does is bypass the boost off the throttle and at cruise, you could hook up a manual one all it is a solenoid that allows vacuum through or not.

I would source a VS loom and computer to suit.The block is made of cast iron and all use two-valve-per-cylinder iron heads, actuated by pushrods. The engine, originally designed and manufactured in the United States, was also produced in later versions in Australia. The was on the Ward's 10 Best Engines of the 20th century list, made Ward's yearly 10 Best list multiple times, and is one of the most-produced engines in history. To date, over 25 million have been produced.

InGM sold the design to Kaiser-Jeep. The muscle car era had taken hold, and GM no longer felt the need to produce a V6, considered in North America an unusual engine configuration at the time.

The energy crisis a decade later prompted the company to buy the design back from American Motors AMCwho had by that point bought Kaiser-Jeepand the descendants of the early continue to be the most-common GM V6 as it developed into a very durable and reliable design. This engine has the cylinders numbered on the left-hand bank front bank for FWD applications and on the right-hand bank, the number 1 cylinder being the furthest from the flywheel end.

The firing order is The uneven firing pattern was often perceived as roughness, leading a former American Motors executive to describe it as "Rougher than a cob. InBuick redesigned the crankshaft to a "split-pin" configuration to create an "even-firing" version. Since the cylinders center-lines were no longer centralized over the crank pin bearing journals, the connecting rods were re-designed with the big-ends offset from the piston pin ends by 1.

The engine in this configuration became known to have "off-center bore spacing". The off-center design continued up until the LN3 version of the engine, when the left-hand bank of cylinders was moved forward relative to the right-hand bank.

Although the actual bore spacing between cylinders on the same bank remained unchanged at 4. Buick Division, concerned about high manufacturing costs of their innovative aluminum V8, sought to develop a cheaper, cast-iron engine based on the same tooling.

In initial form, it had a bore and stroke of 3. Dubbed the Fireball V6, it became the standard engine in the Buick Special. The bore was increased to 3.

It was known as the Dauntless V6 and used a much heavier flywheel than the Buick version to damp vibrations resulting from the engine's firing pattern. Buick sold the tooling for this engine to Kaiser inas the demand for the engine was waning steadily in an era of V8s and muscle cars.

One quick idea was tried by Buick engineers — taking an old Fireball V6 picked up at a junkyard and installing it into a Buick Apollo. However, AMC's cost per unit was deemed as too high. Instead of buying completed engines, GM made an offer to buy back the tooling and manufacturing line from AMC in April,and began building the engines on August The bore was enlarged to 3. InGM began to market the as the 3.

Starting inthe engine was used in the front-wheel drive Buick Rivierathough still with a longitudinal mounting. Larger valves and better intake and exhaust boosted the power output for A turbocharged version was introduced as the pace car at the Indianapolisand a production turbo arrived in The turbo 3.

The LC2 engine has a bore x stroke of 3. The turbocharged Buick Regal Grand National GNX was called America's quickest automobile, and the model continues to be collected and appreciated today. A smaller version of this engine was produced in and for the Century, Regal and Chevrolet Monza.

The bore was reduced to 3. This engine was used in many large rear-wheel drive Buicks, and in some models from each of GM's other divisions, including Cadillac which offered the "big" Buick V6 in several models from to as a credit option to the troublesome V engine used in and early versions of the aluminum-block Cadillac HT V8 introduced in It was also the standard powerplant in the front-drive Riviera and Olds Toronado from to Additionally, the 4.

Its only weakness was the intake valve seals.
