More grounds and hot taps

[sargentrs]

Not my truck, project's stalled, but my '74 Dodge Dart. Really tired of whole hassle of trying to find a place to tap into a constant or switched hot source for things like gauges, cigarette lighter, 12v phone charger, mp3 player, HEI ignition, etc. So I figure I'll run some additional wiring so I have more constant/switched 12v sources. Question is...

Is it good to ground everything to the battery negative terminal? Plan on using these http://www.ebay.com/itm/251795214723 to give me some decent taps on the battery posts and, along with the starter relay and engine block ground, run a hot line to a junction block and from there to a relay to a separate fuse block under the dash. Then a ground line from the battery to another junction block and to a terminal strip also under the dash. Another ground for headlight relays, along with hot taps for those relays, too. That'll give me 6 fused taps for accessories, additional constant hot sources from the junction block, multiple sources for ground both in the engine compartment and under the dash, etc. I'll be upgrading to a 90 amp alternator in the process. The wiring on this car is in sad shape and want to bypass as much of the original as possible. I just had some concerns about routing everything from the battery. Not too happy with the guys over at the Mopar forums so I thought I'd come home to here and ask a great bunch of guys I know and respect. Still picking parts but here's a few of what I've found so far...

Any advice, input, concerns, etc? Thanks guys!

I wouldn't run individual grounds to the battery, a Dart is a unibody, right? A good ground anywhere on the unibody is electrically the same as any other ground on the unibody. To hedge, weld individual ground studs where they are most convenient.

Thanks, HIO!
