Grounding an engine, adding wires to connect the vehicle to the pcm.

I got under the truck and added the ground wire to the starter, I also added a plug from the PCM that will connect to the vehicle and it'll be easy to disconnect the vehicle harness from the PCM harness but also allow all the integration functions like TCC disconnect, fuel pump, OBD2 connector, tach, speedometer signal and others with the ability to disconnect the truck from the engine wiring harness easily.
Hope everyone had a good holiday time, I don't really enjoy it that much I think it's just when you have to go to strangers houses and eat strange food it's just not as fun for me. Y'all be safe on New Year's.
hot rods on roads not on jack stands

Dremel with a cup brush makes fast work of ground contact points. Then, lather the bare metal with dielectric grease. Place a stainless steel star washer between the grounding lug and the body/frame.
I'm currently refreshing all the grounds of my 1993 Chevy C1500. The vehicle is currently experiencing a intermittent engine drop-out once heat soaked. Although I'm pretty sure the issue is not a ground one, refreshing the grounds on this old of a vehicle is a wise move in avoiding future age-related electrical issues.
