Subaru ECUs are mounted inside the cabin, not water tight. Drop it in the trunk, easiest. Or extend the harness and move it to the cabin.

(IMG:style_emoticons/default/agree.gif) I'd put it in the trunk. You need a little protection but no need for it to be sealed water tight. If you extend the wires you have to use high quality stranded shielded wire for many of them. It makes for a very fat harness to pass through the firewall. The shielded wires for the cam and crank sensors are very sensitive. Any significant signal leakage will cause it to run poorly.

I'd think the harness is long enough to put in the cabin, possibly between the seats either on the floor or the back. Easy enough to cover with a shield and some sort of material or pad. That's what I'm planning...

My Nissan will be a little different, but there will still be more fuses & relays involved.

8 relays total. ecu, ign, fuel pump, starter, ac comp, cruise, fan 1 & 2.
14 new fuses: ecu hot, ecu switched, coils, injectors, fuel pump, fans, etc...
This is beyond the chassis fuses & relays. This panel replaces the stock panel in the engine bay.

This is why I don't have a build thread, can't find a finished pic (IMG:style_emoticons/default/headbang.gif)

40 plus yr. old wiring with those crappy fuses and no room for relays? Nope... not for me. Play with the wiring lengths that you have, see where you can go, and fit it as safely as you can. If you need to have it in an exposed area, install it in a box where it can be accessed quickly and that's fairly waterproof. Preferably up high would be best.

(IMG:style_emoticons/default/agree.gif) Listen to these 2 guys. There both mechanics. You can't have too many fuses or grounds or relays. My Dakota Fan Controller instructions were quick to point out that the relays (switched & hot) could not share the same circuit or bouncing was likely. I experienced this once when I designed my own neutral safety switch. The computer went wild and so did the idle circuit. I didn't know why then but now I understand. This is what happens when a plumber ventures into the electrical world. (IMG:style_emoticons/default/av-943.gif)

So I need a fuse system for every wire I intend to use,.,( for instance) I run a starter wire to a fuse block or panel and then to the actual starter lug,.

I thought fuses were for hi AMP draws,..?? Thanbks

Your ECU needs to be protected on the positive switched side and the positive Batt side. Any appurtenance that you're adding that requires 12V needs to be fused e.g. after market gages, radiator fans, fan controller, AC, etc. Fuses are sized to the wire size and the wires are sized according to load. I did not share fuses as the OEM setup is antiquated. You'll end up with 6-12 additional fuses depending upon additional circuits required. Hopefully your running a fused 8ga wire from the engine bay to the trunk for your fans. (IMG:style_emoticons/default/beerchug.gif)

ECU wiring for a 97 Maxima. Suby likely pretty close being from the same design era & obd2. Basically any component that can short out gets it's own fuse, otherwise figuring out what failed would be a nightmare.
Fused distribution blocks cheap on ebay.
I essentially recreated the factory setup.
I also added an 8ga from battery to a distribution block next to the factory fuse panel, for the 2 fans and added electronics.
I also added about a dozen wires to the dash for VSS, water temp, fan triggers, a/c button, CEL, etc.

red = battery hot. orange = switched. yellow = start signal.

That's an excellent point Chris. I always just thought of it as "fuse anything you don't want to burn up". Never thought about it from a diagnostic stand point. (IMG:style_emoticons/default/beerchug.gif)

Clutch is behind the Pressure Plate which is bolted to the Flywheel which is bolted to the Crank which is not attached to the Adapter. The Adapter might slide over the Flywheel though it will be a tight fit.

I didn't have to recreate anything, just adapt it to a few existing systems on the car. I pulled my stock wiring altogether and am using most of the harness from my SVX including the instrument cluster and the steering column similar to what Andyrew did. I intend to drive the car across the country and am basically a wimp, wanting to have as few issues as possible that I'm not familiar with. I'm not nearly as adventurous as most of the folks around here!
