4l60e swap wiring Hi everybody, not sure if this is the right forum. I'm just about finished with my t-56 to 4l60e swap and I just need a link to the shifter wiring diagram form those that have done this. Thanks for any help!

The 13 or 14 wire harness from the trans to the PCM is all that is needed.
By "shifter" do you mean the black electric box that some 4L60E/4L80E have? That box only implements the reverse lights and the Park/Reverse interlock.
If you want details on how a factory 4L60E is wired through that black box, you need to tell us what year and vehicle you have.

It has been almost 2 years since I have done this and my memory is a little fuzzy. My car was is a 2002 Trans Am and the donor was a 2002 Camaro.
** Please note that the diagram of the C220 behind the right front kick panel shows to different color wires going to the H terminal. (Orange/Black and Light Green) I can’t remember which is correct but you should be able to figure it out. If you get stuck I can pull the kick panel and check.
Back-up light wires are in connector C220 behind the right front kick panel. Run the Brown wire from the G terminal and the Light Green wire from the **H terminal of the C220 connector behind the kick panel to the Park/Neutral Switch. The Brown wire goes to the C terminal and the Light Green wire goes to the D terminal on the Park/ Neutral Switch.
Dark Green and Purple/White wire from clutch pedal switch that is closed when the clutch pedal is down should be ran to Park/ Neutral Switch terminals E and F. I don’t think it matters which one goes to which terminal.
For the TCC and Cruise Control to work properly the Pink and Purple wires from the clutch pedal switch, that is closed when the pedal is up, should be run to and A4 bake light switch that is closed when the brake pedal is up. The Pink wire comes from the C terminal and Purple wire goes to the D terminal of the C220 connector behind the right front kick panel.
You need to run the Orange/Black wire from the B terminal of the Park/Neutral Switch to the **H terminal at the C220 connector behind the right front kick panel.
Run the Black/White wire from the A terminal of the Park/Neutral Switch to the E terminal of the C220 connector behind the right front kick panel.
When wiring up the Shift-Interlock solenoid you will need to run a Dark Green/White wire from the part of the brake light switch that opens when the brake pedal is depressed, B terminal to the B terminal on the Shift-Interlock solenoid. Now run an Orange/Black wire from the Shift-Interlock solenoid A terminal and tie it into the Orange/Black wire that runs from the B terminal on the Park/Neutral Switch to the **H terminal on the C220 connector. I tied it into the Orange/Black wire at the C220 connector. You will need to install a diode in the Orange/Black wire from the A terminal on the Shift-Interlock solenoid to where it ties into the C220 connector behind the right front kick panel (see diagram).
I pulled all of these wires and connectors from the A4 car that I had, especially the Orange/Black wire with the diode in it.
The shifter cable that only moves when the button on the shifter handle is depressed goes to ignition switch or the steering column, not the shift indicator like I said before. This keeps you from being able to remove the keys without the shift lever in park. You may be able to just use the A4 ignition switch instead of replacing the whole column. I had the column so I used it and I didn’t like the lever by the lock cylinder that you had to push down to get the key out.
