We have had many discussions about wiring cars, floating grounds, etc, so here are some pics of a recent job. First pic is "floating ground". All grounds in car come to this buss bar. Nothing grounded on chassis

Nice Monte thats how I did my grounds this time.

Monte I like that set up. Where can a guy pick up that buss bar?

More pics. Coil packs and outside grounds. There are multiple grounds out front for fuel pump, fans, water, lights. They all ground on this stud and then heavier wire runs from here to inside buss bar to cut down on wiring. Crank sensor wire is run inside main rail to isolate and eliminate RFI. Last pic is crank trigger dist modified to be a cam pickup

It's for a boat, but I have made my own from copper strap. Simply make a strap, drill some holes in it with several bolts for ground studs and mount it to the chassis on rubber isolators. I was out of copper and found this piece........but it worked nice

The Reaper?

This forum is very aggravating to me anymore. None of the pictures are loading on this thread at work. They load on some other threads. I don't get it. Most of the time the parts for sale pictures don't load.

I checked my phone so I got to see the beautiful work, just a smaller version of what I should be looking at.

Monte, you do nice work. You should get paid for it

Monte.. I see you drilled a hole in the chassis
tube.. I didnt think that was allowed... plus you
forgot the grommet.. the whole job looks good

Nearly all pro built cars have wiring, fuel, brake lines, whatever run inside the frame rails. The grommet is in it now.


Don't worry Ray........I DO.........LOL!!!

I didnt know that holes were allowed... wish I would
have known that long ago

Very nice Monte

Nice job, Yes the buss bars can be picked up at most marine supply stores. They have many sizes, at least the place I got mine at did. Boats have so neat switch panels also . I used them as shown for the grounds and for misc. hot wire interior gauge lights.

I love to see how others (Professionals) do this kind of work. I had issues in the past with the electrics on my old racer. I am trying to absorb as much as I can and apply it to the new ride (My Junk), but it won't be as nice as this.

Wiring is NOT hard, if you understand how things work. Just time consuming and hard to make look nice. Mine never looks as nice as I WANT it to.

On EFI cars I always use the unterminated universal harness and build my own, because to me, the plug and play harness looks like an octopus and I don't use near whats in a stock harness anyway. You can look at my ECU plugs and see I use the bare minimum and pull out anything unused

The biggest problem with most people wiring a car themselves is, they think zip ties are expensive...

Nice work Monte.

The good ones aren't exactly cheap! haha

I am finishing up a small wiring project, and the wiring doesn't look horrible, but definitely doesn't look as good as I would have liked.

Nice work Monte!

Outstanding work Monte!

not trying to hi-jack, but is there a proper orientation to a relay? As in right side up? I thought I read somewhere that the g forces of a drag car could cause the contacts to open under acceleration.
