Some gangbangers out of South California try to run me to town by burning my truck down they only succeeded in bringing the interior and dashboard I am trying to figure out what the electrical color coding for the wiring harness is coming in to the cab from the engine bay

 

Theres about 100 wires on the PCM (RH firewall), and another 100ish on the LH bulk head connectors

 

I think your best bet would be buying an entire donor harness and just swap everything over that you need
