LS2 TB wiring harness problems
Has any one had any issues with the LS2 TB harness adapters. I am finishing up an LS7 conversion and have several TP sensor codes. I have had several issues with the CMP sensor harness on LS2 conversions so I assume it is the adapter harness. Has any one else had this problem? It would save me some time on the diag.
Thanks, Dale

Pin letters on ls2 tb/oem wire colors
A/brown (stepper motor)
B/yellow (stepper motor)
c/darkgreen (TPS Sensor harness)
D/dark blue (TPS Sensor harness)
E/purple (TPS Sensor harness)
F/pink (TPS Sensor harness)
yellow and white not used (TPS Sensor harness)
yellow and white wires on the old harness are redundant wires used by gm and arent needed just tape them up.. I had to use this on both swaps let me know if it works for ya!
