got some more work done. finished up most of the engine bay wiring. gotta mount the high & low beam relays under the battery tray and wire up turn signals & headlights.
Heres some pics of how I mounted the E-Z wire fuse box, right in the factory location. took me a while on how i was gonna do it, but used some 1/8" thick sheet metal. it's pretty solid. dunno where else I coulda put it.
For the grounds I used an 8 GA wire, from V/R to back of drivers side head, wiper motor to passenger side head, and from negative post to the head and radiator support.
