Possible Useful Link for ThirdGen Wiring -
#4
Hi, Vader I had talked to you about the electronics on my car, now if you can help me with an engine swap? I have a 1983 Trans Am original 305 Cross-Fire Fuel Injected, I want to swap it with a 350 Tuned port motor from a 87 GTA. Motor is complete, including pulleys, alt, a/c, p/s, exhaust manifolds, dist, engine harness, computer, complete injection, mas air sensor, and motor mounts. Will this work will I need to change anything else?? Fuel Pump, exhaust system, catalytic converter?

Those diagrams are for a Firebird.
I just had a question about those diagrams. I have a 91 Camaro RS 5.0L TBI. How will these diagrams compare to my car since they are for a firebird? I've been told that they are basically the same car. It would make sense though that the differences between them would be small/electrical.
Please help, I'm getting ready to pull my dash to swap it with a 4th Gen.

88F/Bird wiring diagrams
Vader,Thanks for the reply. My engine is a carbureted 355,and the high stall converter is locked up manually by a modification to the valve body involving a plastic check ball in a passage under the lockup switch.Works well,lockup is very firm,but not excessive.High Tech Transmission in Houma,did extensive modifications to my trans,and it has taken a good trouncing over the past two years,and still works just like it did when installed.
Thanks again,
"The Accelerator"

Re: Possible Useful Link for ThirdGen Wiring -
Hello. Do any of you know where I can get the pin outs for the engine to under dash wiring harness. I already have the pin outs for the ecm and have all that worked out but It is the harness that would connect the computer and the engine wiring harness to the underdash wiring harness. Please help me out if you have any information. I am stumped right now.

Re: Possible Useful Link for ThirdGen Wiring -
Ok, I looked through a couple of the diagrams from up top. It looks to me that if I can find a 90 or 91 3.1L V6 engine harness, I can use it for my basis for a TPI retro fit. I would only have to add a couple injector plugs and do away with the temperature switch for the tranny? This maybe easier than trying to repin a tbi harness? Yes, no any thoughts, thanks.

Re: Possible Useful Link for ThirdGen Wiring -
try these guys at Automotive Hobbyists (info@ahdol.com) - i paid 11.99 and i got an entire colorcoded set of diagrams for the entire car, which is a 90 camaro. does not matter what model they give you everything for that year.
EVERYTHING!
best 12.00 i ever spent on the car. and it is e-mailed to you so that you download it and only print the pages you need.

Re: Possible Useful Link for ThirdGen Wiring -
Unfortunately, they now require you to register. Get to a point and select "Repair Guides", and they'll have you register. Then you can see all diagrams for all 82-92 of the model you've selected as your car.

Help with speed sensor wiring
ok, so heres the story... I started an engine fire and fried the computer wiring harness to the girlfriends 1986 Carberated 305 HO along with burning lots of other components...long story short we went back to vacuum controled while upgrading the cam, timing chain and cover, valve job, intake manifold, holly carb, valve covers, headers and new vacuum distributor...now we have an issue with the speedometer not working (since it was computer controlled) so...is there a way to bypass the computer and hook it up directly or is there another option besides going back old school with a cable on the speedometer?

Re: Help with speed sensor wiring
so the fire never got through the firewall behind the engine but burnt up the cable going to the transmission (the speed sensor cable that runs to the computer which we pulled out). The speed cable going to the cruise control is intact and the wires going to the c100 were all ok...so in order to get it running I have to splice some wires? to where? I think I have to get a new sensor clip also since it burned up...

Re: Possible Useful Link for ThirdGen Wiring -
Through work, I can look up any wiring diagram in mitchell. If someone could narrow down how interchangeable the wiring is for third gens, I can try to put them here for all to see. Its just a lot of diagrams to copy and paste.

I need the diagram for the plugs that are going to the ecm from inside the dash for a 91 rs v6 and also an 89 rs v8 305 tbi.
If I had the diagrams for bothe cars I could probably figure it out.
They seem to differ and I'm stuck.
Thanks for your help.

Re: Possible Useful Link for ThirdGen Wiring -
I have an 89 camaro 2.8. It appears as if a wire is missing from the rear of the alternator. There is just a connector with no wire. Do you know what this wire would do? The guage just shows an 8 not the 13 it used to. I am at a loss because I can't find a disconnected wire. Please help??
