wiring help needed

Ok so the harness is almost completed but a couple questions, on the stickie about modding the original harness for the LS1 swap it says to connect the TCC to R2, now which TCC? on the C100 pin E7 is a TCC and also on the C207 pin H is also TCC. Also R2 is the TCC solenoid so shouldnt you connect the TCC to pin B33 TCC brake switch instead?

Re: wiring help needed

I had to think about your question for a while. I think you pointed out an error in the write up

Here is the 3rd gen TCC circuit

Here is the same for a 4th gen

R2 goes to the trans connector and B33 to E7 on the C100

Pin H on the C207 is not used

Guide has been updated
