Hi guys

Starting on a new harness modification. its a 2003 lq4 harness with blue/green connectors from PSI.

Trans will be 4l80.

Wanted to know what Green pin 42 TCC Solenoid Valve Control goes to? Its a tan wire

Right now, it looks like it goes to one of the 4l80 VSS's (tan/orange wires)

Is that correct?? If not, where is green pin 42 supposed to connect to?

Doesnt match the lt1swap that ive used in the past.

And, where is the other VSS supposed to connect to?

Extra information:
green 20/21 are the green/purple VSS to trans
green 22/23 are not currently being used

thanks guys

little more research points me to the TCC Solenoid Valve Control should be pointing to pin T in the big round trans connector?

And currently, there no pins in trans connector T,U,V,W.

Did PSI mess up here?

Shouldnt T be connected to green 42?

Shouldnt V be connected to green 2

And should the orange/tan wires of the second VSS go to green 22/23?

ok .. some progress.

according to this:

http://lt1swap.com/4l60e_4l80e_harness.htm

green pin 2 goes to trans connector pin s. which it does

But, the ISS connector (PSI tans and orange wires) need to go to green pins 22/23. So looks like PSI did half the job.

lt1swap rules!!

Please post up how your progress goes. I will be converting to a p59 Blue/Green soon and changing to a 4L80e from a Red/Blue 4L60e.
