Help with rewiring Leeloo Options

[nine14cats]

Hey Guys,

I need some help in rewiring Leeloo. Instead of cutting down the factory harness, I'd rather just make another one as the wiring is vintage 1971 and pretty gross. Since I'm really cleaning the car up, it seems to make sense.

The scope of work is to wire the car as a race car. Ignition, brake lights, etc., but no other lighting. I plan on putting in a digital dash (AIM, Motec) and running a Traqmate for datalogging as all of my files from my previous cars are Traqmate. The car will have a toggle switch power on with push button starter circuit.

Questions:

1. What gauge wire and where can I purchase bulk with various colors for a good price?

2. What brand fuse panel? Do I need a fuse panel?

3. How many relay's needed? Where is a good source for that?

Leeloo has been undergoing a slow but substantial transformation. Mostly we have put her on a diet to make her lean. Roger Sheridan top and lids for the weight reduction and gutting the doors and dash. I also had her 901 refreshed with a new R&P, new syncros, new bearings and a Wavetrac TBD installed. Yesterday I picked her up from TCDesign with her new cage installed, including chassis re-enforcements and shock tower tie ins at all four corners.

I'm going to weigh her later today and take a few pics to share. I still need to decide (and save money for):

1. Shock choice
2. Tire and wheel combo's/sizes
3. Body work mods, including flare sizes and aero (wing)
4. WEVO 915 (I have the 915 box, I just need to start purchasing the WEVO bits)

I think due to my work schedule I will be primarily running the car in PCA Club Racing for the near future, so the car looks to be placed firmly in the GT3 class. Body work wise I really like the GT look, but it won't allow a very large tire on the car. I'm thinking either cave in and use Sheridan's FG and start hacking into her or using a body guy I know to widen the flares like my old 914, JLO.

Here is a pic of JLO with widened GT flares that accomodate 22x10x16 fronts and 23.5x11.5x16 rear Hoosier slicks on 16x10 rims:

Any help on the wiring questions would be greatly appreciated!

Thanks,

Bill P.

Wire size is totally dependent on amperage draw and length. You have to figure out what is going to be on each switch and go from there. No relays are needed. Plan for an extra circuit in each area (one front, middle, and rear) so you have them in the harness and don't have to add to it.

In my opinion, it's worth spending a little more and getting all top notch products. Get aircraft breakers, wire, and switches. Use high quality terminals where needed and Deutsch connectors. It will add a little bit of money (a couple hundred bucks) but it won't fail later and is small money versus the labor involved.

Wirecare.com is great for heatshrink, prowireusa.com is great for wire, switches, and breakers. Also check out http://www.rbracing-rsr.com/wiring_ecu.html for an idea of what goes into a top level harness.

As to the data - a MoTeC or AiM dash will do the logging, so no need for the Traqmate. Also, it's very important to plan it all right now so you don't run redundant wires. If you have an AiM or MoteC system, it will display and record all the engine metrics (oil pressure and temp, RPM, etc). The analysis software is also much stronger on those systems than Traqmate.

I'm an AiM dealer - shoot me an email at matt@trailbrake.net and I can help you with planning out your dash/data needs. I did this to our car 2 years ago and it was the best thing we've done to it.

Here are a couple photos of what I did.
