So if I'm honest, I wasn't really feeling into wiring tonight. The car is across town since I'm dog & house sitting...and, lets be honest, wiring isn't exactly the most exciting option out there! But, I have a rule about spending an hour a day...so over to the shop I went. Arrived before 8...and after I started, ended up wiring until midnight before I noticed the time. After some help from the motorgeek forum I found the relay mounts I'm going to use, and decided that my relays will get mounted to the front face of the fuel tank support, underneath my 'strut bar'. It's the most logical location for 2/3rd of the relays that I'll be putting into the car. These include the fuel pump, headlight and rally light relays. Since there isn't a "clean" spot to put my dash-related relays I'll drop those down there as well.
With that decided I was able start reworking the front half of my harness. First off, I ended up removing the stock headlight wires completely. Since everything will be relayed I only need to run two trigger wires from the fuse panel, and they can be relatively light gauge wire. After those were removed, I started adding wires in. Most of what I ran could have been done with 22ga wire, but I tend to only keep 18ga and larger around the garage. A little overkill, certainly heavier, but I'll survive.
Wiring added:
Lights
- Low beam trigger wire
- High beam trigger wire
- Rally light 1 trigger wire
- Rally light 2 trigger wire
- Rally light 3 trigger wire (future upgrade potential)
Fuel Pump
- Tach Signal wire
- Selection switch wire x2 (fuel pump selector switch pump 1 or 2)
Rally Computer
- Power feed x 2
- selection trigger wire x2 (allowing me to choose between ignition switched power source or direct battery power source)
Dash
- Oil light trigger
- Oil light power
- Gen light trigger
- Gen light power
- Turn Signal indicator trigger
- Turn signal indicator power
(The above allow me to use any gauge combination I desire, and still have working warning lights)
Other
- Spare wires for future additions x2
- 4ga power wire direct from battery
- 4ga power wire from fuse box (ignition switched)
So looking from the bottom up...the first two loops are the turn signals, L&R. The next loop consists of all the new wires I've added, which will end up hidden under the spare tire. The next loop after that is the "Mid harness" which goes to the Voltage Regulator. Above that are the wires that will make up my switch panel. I think I'll end up putting it where the stereo would normally go. And then there is the fusebox and the wires for factory switches.
Here is the harness being test fit into the car:
My relay mounts will be in on Thursday, and by then I'll have decided on the circuit breaker mounts. Definitely will need to find a "wiring cover" for the 1302 (or make one), as the behind the dash area is going to still look like a complete rats nest. Especially once I add in all my gauges!
