Basic wiring schematic for a race car?

Does anybody have a schematic for a basic wiring loom, with headlights, wipers and basic engine wiring for a carbed vehicle.

I need to rewire the Mustang and need to be sure I get it right the first time.

Steve

I don't right now, but I'm going to keep an eye on this.......I'm going to rewire the ti's lighting system separate of the engine harness to expedite different engine configurations.

I'd just put everything on a different switch run to whatever relays you may be using. My cavalier only has two switches and a button. Ignition, fan, push start. No lights, though. If I were to put some in, I'd just add a separate switch with whatever relays it called for. I can draw up a schematic later. Can you tell me exactly what you are running power to? Just engine, wipers, and lights? I could probably build one as well given proper dimensions.

If you're running a 1/4 turn master cutoff switch, make sure you run battery, ignition, AND alternator/generator through it.

do you desire turn-key with original switches for stuff, or are you going with toggles and buttons and such?

i'm sure i've got something at home i can scan and send you, from the V8Vair and/or the V8 944.

any chance you can get a copy of your wiring harness?

I got a copy of the original harness, and erased what I didn't want. Then fabricated it.

I would just run each circuit as needed, and then loom it.

Unless you already have a bunck of the wiring I dont know if you could beat a premade 12 circuit kit as a start. I rewired a truck with a Painless kit but if I were to do it again I would buy one of these. They are cheaper and I helped install the EZ branded harness in another truck owned by a friend. http://www.ezwiring.com/wiring_harness.html

i assume you mean 'diagram' instead of 'harness'.

that's what i did on the V8Vair, then i pretty much used the V8Vair diagram to design the V8 944 harness.

In reply to AngryCorvair:

Its a challenger Pat, no need for a key start, anything you can offer would be hugely appreciated.

Awesome deal but still not challenge friendly... enough.

Helps?

Edit: To be honest though, The carbed cars wiring harness isn't that complicated to begin with so I doubt you'll remove much weight.

86 5.0 efi car has 25lbs of wiring. Plus the original loom was hacked up and scotch locked.

Resurrecting this because the old loom is out and the new starts when I get the caged shell back

do you have the OE ignition switch, wiper switch, turn signal switch, brake light switch? do you still have the original (albeit hacked and scotch-locked) harnesses for the whole car?

Yes I have all the old parts, pretty damn heavy too

For some reason when you look up dune buggy wiring kits, they seem much cheaper.

Is keeping wipers a judging benefit? or?

In reply to Gasoline:

I deleted mine......they weighed too much.

Thanks! I will keep in in the bottom of the 55 gal junk drum.

For Steve: This is a pretty basic idea (w/ relays) for a race car

You need this one also: GoGo

I thought we were required to keep wipers and lights on Challenge cars...

This is all I saw:

'6. Cars must be roadworthy, meaning basic street equipment must be present: functioning headlights, uncracked windshields, battery tie-down straps, working brake lights, working horn and DOT-approved tires.

In reply to Gasoline:

berkeley, the ti's horn quit working, so it was removed.....will a small hand ball horn work?

you would not be the first to employ a manual horn on a challenge car.

Did the same in the RX7 race car
