Been searching for a while here with no luck... All is working really well and runs great, save for NO TCC lock up.
My 1993 K1500/4L60E now has a basically stock LT1 motor now ( 383 with a 4x4 torque cam ), I used a basically stock F-body harness.
I have used a couple different bin files for a 1994 LT1 Automatic, knowing my 93 4L60E is NOT PWM. I have checked and rechecked all my pin/connector locations and all is good as far as I can see. All my Bat+, Key+, and Ground circuits are good.
Some of the stock inputs from the F-body harness I have not hooked up, because, #1 there is no place to use these on my truck AND #2....I don't know what some of them do.
I can while driving ground the TCC lock up wire and I do get TCC lock up. So for some reason the PCM is not commanding lock up?
Inputs/Outputs that are NOT connected: >>>
1- PNP Grounded or not, still no TCC lockup. No PNP in my truck, the neutral safety feature is not electrical. The key wont turn to start if your anywhere other than neutral or Park.
2- EBTCM TP...Not sure what this is or how it works?
What I do have wired up and working.
Brake switch circuit is good.
VSS to and from PCM is good, my speedometer is working perfect. ( I have other questions about this, and getting my cruise control working again....just not as important as TCC Lock up. )
What qualifiers does the 16188051 need to ground pin 11 Tan/BK wire in PCM BLUE connector?
Sure would like the TCC working...
