Got that stuff covered Cab just thinking about a small wire from the batt directly to the stud on the firewall which the MSD and all of my other grounds go to..............Probably not needed I guess.
I ground everything back to the battery using lugs and a grounding block, See ground block in the lower left of the panel. (progress pic)

Wow looks good, need to do my car one of these years! I think your plan is a good one.
I have that same bank of relays in my Rampage... it is a nice piece... it controls my head lights, fan, water pump... being a tube chassis car I have a stud welded to the chassis back near the battery and one welded to it near the engine on the drivers side.. I ground the engine off of the engine mounting ear and and have another stud inside on the knee loop on the passenger side... that point is for all the inside electrical stuff

No better ground than the frame. Bolt to your rear subframe. It's welded to frame connectors which are welded to the front frame rails. If you've got a problem with a ground then you've got worse things to think about. You won't find a ground to the front in a new Charger or Challenger that have the battery in the rear. Trust me, new cars have way more electrical issues to deal with than a simple car like what we both race. In case your wondering, I work in the Electrical lab at Chrysler Tech Center. Doug
sorry but thats absolutely not true.

I'll take my tube chassis any day for a ground

ok,i'll keep running a good copper wire up front and use that there is a reason all the electronic device people tell you to do that I think.

I've been doing this for YEARS... the area of the tube is more than sufficient plus amps make heat and the tube is exposed without any insulation on it... the old frame cars thats way different.. they have spot welds holding the metal together... I dont

I'm willing to listen, why is a solid welded piece of tube steel a bad ground? I could understand it if you were using a stock spot welded 40 year old unibody. We run way more sensitive wiring in current vehicles, CAN Bus ETC.Chassis is the prefered ground. Doug

No better ground than the frame? We're talking cars/trucks with the battery in the back, MSD (or EQ) somewhere in the middle. Maybe in a stock situation where everything is under the hood the frame would work.
But I tried the frame, no thanks.
New Chargers and Challengers do have the battery in the rear. How many computer modules do think each one has? The slightest interference drives them nuts. A good ground is absolutely necesary Doug
