Trunk Mount Battery - Wire Routing

Send a PM anytime. There are people on here a heckuva lot smarter than me but I'm always willing to lend a hand.
To answer your questions...pencil & paper. And an eraser too!! Relays for all high current items - fuel pump, separate ones for the twin rad fans, trans cooler fan. Maybe do the headlights next time like Crackedback on here sells a harness for. My car was a strip car that I made into a street legal car so that is why I started from scratch and stripped EVERY wire out and tossed them in the trash to start.
