ECU location for Fox/LS swaps? Where is everyone locating their ECU's on Fox/LS swaps?...Are you having to extend your wiring? I'd like to mount it inside the car and keep the engine compartment clean...Let me know..Thanks

On my 90 LX with using a speartech'd 01 camaro harness I ended up with just barrrely enough room to mount it against the firewall just above where the passenger's feet will be. If you have the heater box out, it makes things a lot easier to keep it "up in the dash" and out of the way. If you want to take it any farther, you'll need to extend the harness.

For what it's worth, we provide 4-5 ft of harness length from the rear of the engine to where the PCM mounts.

Depends on which harness you are using? F body or are you using a Truck setup? Truck harnesses are a gaudy in stock form and put the pcm in a junk location for a fox, however, you can pull the wiring from the pcm back around where it runs to the intake, and instead of extendeding 40 wires to the pcm, you can elongate the Alternator, tps, iac, cts, injectors, cam sensor to fit, which is only 28 wires to extend about 4 ft to put it in the passenger kick panel. Not too hard to do once you unloom the whole harness and have it sitting in the car.
If I had a stock harness to work from, I'd save the money, convert it, lengthen it, shorten, etc., because building a sub fuse box only cost about 50 bucks in materials tops, but if you had to buy a harness, I wouldn't waste the time, Id spend the money on a PSI harness as its already longer than factory and nearly plug and play
