Examples of wiring harness installs and fuse box locations; maybe some pics please?

[66Tempest326]

Hey guys, getting really close to the point where I will be ready to order a wire harness for the car and was hoping you guys could maybe throw up some pics of where you located the fuse box and how you wired up the dash.

Based on what I have read, I believe the AAW kit is right for my needs, so...

Here's where I am,
Car: 1966 Pontiac Tempest Custom
Engine: LS1
Controller: PSI harness for a DBW LS1 (Alternator control, fan control, fuel pump relay), which will mount on a flat plate under dash; likely the DBW box will mount on the underside of the same plate (firewall is smoothed so I don't want to mount anything else there; DBW pedal is mounted to studs we welded to the firewall and bodyworked) - basically supply power and a ground; side note water temp sensor in stock location used by this harness for CPU monitoring.

20 gallon fuel cell with Aeromotive Eliminator EFI (just in case I ever decide to add a blower or turbo, got plenty of fuel)

Air Conditioning: Vintage air unit direct fit (glove box removed and smoothed out, so no issues with room) - again, basically supply power and ground
Headlights: converted to halogen bulbs in a sealed beam looking housing; included are pigtails to plug into stock harness
Taillights: stock replacement
Windshield wipers: Raingear hidden system - requires reverse than factory harness wiring (more of that later if anyone needs)
Everything else: gutted and thrown out, I mean EVERYTHING: courtesy lights and switches, dome light, brake switch - it was all dry rotted and grounding somewhere

Gages: Thinking Speedhut for the ability to customize.

Speedo with GPS is cool, no additional hookups;
tach - no clue, suggestions?;
water temp - how to do this with the stock location already taken up?
Oil temp - stock location at oil cooler bypass available (already has a GM electrical sender installed)
Oil Pressure - stock location behind intake manifold available (already has GM electrical sender installed)
Fuel gage - sender in the fuel cell


Future: I would like to add a nice radio, nothing fancy, maybe something double din to look more modern sized, with blue tooth and USB plug in and charging, good speakers (not into boom boxes, but back seat is deleted and blocked by roll cage so something could go there.

Comments, feedback, questions, and hopefully pics please.

I would suggest the AAW update harness, if available for your car. It has a gauge harness kit, but you will need to tailor it to your dash/setup. I have only used auto meter electric gauges, so this info applies to them, may or may not work with others. Auto meter makes LSx adapter fittings for oil/water sending units. The oil pressure fitting goes in the the rear of the block behind the intake (stock location). I use a small piece of straight brass pipe off the the adapter, then a 90 deg elbow to mount the oil press sender. This will help clear the intake. The water temp will go in the pass side head in rear. There is a threaded hex plug from the factory that can be removed, and the adapter threaded in. Temp sender threads directly into adapter. Shop that builds my engine harnesses provides outputs for the speedo & tach. I wire them directly to the signal port on the gauges. I mount the ecm, fuel pump relay, and vintage air relays above where the glove box liner would be (this is in a first gen F body). Fan relays I mount hidden inside the fender or hidden area of the core support. They could be mounted under dash as well though.
