Onto another issue.. and looking for some much appreciated help. I was quite eager and foolishly cut the passenger through firewall harness and removed it from my harness when ditching the 4.3 for the 5.3 swap. I have been messing about with grafting a stand alone harness ever since. The truck runs well, most things work but I'm looking to reinstall that harness through the passenger side to get my heater functioning again. I have not been able to get my tach to work with the white wire coming through the driver side plug either. (Tried 1k resistor) Verified signal with an aftermarket tach and my signal wire from pcm works as it should. Volts on the dash doesn't work, and fuel gauge has me stumped too. I have put a fuel gauge on the pillar pod that works but I want that spot for boost controller now if anyone has a pinout or diagram for the few wires that come from the passenger side harness that would help alot. Thanks again.
