Well i just got the motor/trans in my car and now comes the wiring. I can only get power to the interior, exterior lights and ignition switch by back-feeding the fuse box. There was a bunch of wires cut out when i bought the car and it now has a carb'd 350 in it. How do i get a supply of power to the fusebox without rigging a direct wire to it? This is on an 84 trans am.

 

Find a new 84 harness that hasnt been attacked by Cleetus

Fuseblock is powered by one of the large red wires that goes to the C100. The other feeds the IGN switch. Last ditch effort you can simply run a new power wire outside of the C100 to the fuseblock

 

Actually, i figured everything out today. Got er' runnin beautifully and all accessories work also.
