Re: Additional swap information

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

Re: Additional swap information

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?

Re: Additional swap information

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/2001_PCM_CONN_PINOUT.htm
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

Re: Additional swap information

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

Re: Additional swap information

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?
