Reply to "wiring approach"

Your approach may be dangerous, in that most people have a 3 month attention span on car modifications. After that, it ceases to be fun and becomes a chore to be avoided. I personally know of two Panteras who's owners got disgusted with the crummy Lucas wiring, and decided to convert the whole Pantera to MIL-spec wiring. Neither car has turned a wheel in a decade..... There are 3 or 4 'official' wiring diagrams; pick the one closest to the build date of your car to start with, then annotate it as you find a varient in your personal Pantera. There won't be many. There are two sources for modern fuse boxes one is Larry Stock in Reno. I'd start with this mod. Second would be to check the connections between the fan motors and the relays, or the fuse box, and be sure you are getting fill voltage to your electric radiator fans. Make corrections as req'd. Third might be adding relays to your headlight circuits, since now 100% of the current goes thru the headlight switch which is known to fail unpredictably with stock non-halogen bulbs. Worse, the bright/dim switch is incorporated into your unreplaceble turn signal switch assembly... I know of only one source for custom built headlight relay panels- Rick Moseley in CA
