hi all just joined and my need of help is how to get power to the cab of truck. think starter relay is bad now is this were the power supply comes from? long story short right now is we been rebuilding and dog house is off its been a year long process father/son project for son. can jump or cross wires to get to starter to turn but still no spark or no power to cab of truck, got manual but looks like chinnese to me not a good one guess covers to many years. but got after market intake and things that don't use factory harness hook up so going to have some left unplugged but needing to know basic s or main plug ups. thanks just ready to fire up for a few
