Hi finishing up my lt1 w/ 4l60 e swap. With painless 60502 harness. On my 1989 T A.
Just a couple thing not sure about.
I need to get my speedo working read on a 3gen post that I need to connect VSS out to the green wire on the vss buffer.
Finally the last thing I need to get my torque convertor lock up working
Open to any suggestion.
Thank you Michael

Connect the speedo wire from the PCM to c207 pin k and connect pins c&f on the buffer box together

Tcc is part of the 4L60E wiring, there is nothing extra to connect on that circuit. The p/neutral wire needs to be connected at the c207, but I forget the exact pin

On several of the diagrams the wire color changed from one side of the plug to the other ( dash harness vs. ECM harness.) In this case I used the DASH harness color ( some Engine harness side wire colors in ( ) ) . I did not take the time to pull out each of the dash harnesses - so It's possble that I missed a wire or 2. If anyone spots a problem just let me know and I'll edit.



Hope this helps !

I found a difference between this diagram and the wiring schematic on LT1swap.com

TPS wiring pin numbers are different

As shown above:
Black B60
Grey B8
Dark Blue R24

LT1swap.com:
Black B54
Grey B46
Dark Blue R24

Anybody know which one is right?

Fbody vs truck pinouts change slightly. FWIW, mixing and matching low ref/5v signals or even tying all into a single pin is acceptable to an extent. The red/blue trucks used the exact same PCMs as 99-02 Fbodys

Compare

http://www.lt1swap.com/99-02_vortec_pcm.htm
http://www.lt1swap.com/2004vortec_pcm.htm

Heres a green/blue GTO pinout that follows the Fbody pinout closely

Pocket THANK YOU so much for all your info I am installing 86 vette MAF engine in my 91 RS TBI car and this is so valuable to me. Is there any other details about that C100 or other things I may need to know not covered in in this thread that you might be aware of between years of this swap. I know it won't be easy But I am retired old guy and have time LOL. Thanks Again Mike

So quick question. I been reading through various threads on various site to get a grasp of my wiring before I do my swap. It'll probably be a 5.3 . Anyways car was a tpi. Then carb. Several years ago I believe I ripped out my c207 , as it was the passenger side harness , correct? So do I need to get one from another camaro. Or I make my own harness with new connectors?

83z28crossfire

Can anyone help me with my current situation. LS1/4L60E swap into my 92 camaro. The motor is from a 04 corvette. I have the stock wire harness. My question is, Can I use the stock harness to get the motor running, or do I need to go out and purchase a stand alone drive by wire harness?

You can use the vette harness. You can either modify it to fut directly to your C100 or route it another way. Lots of ways to do this. I would spend some time reading the wiring stickies before you tear up the vette harness.
