So far, I'm for about $1,200'ish. That's the ECU custom built by DIY AutoTune, Coil packs, Simulater board, and few other parts. I also bought a Weatherpack connecter kit and crimping tool from them. Most of the wires for the harness I bought at a surplus store. Total cost there was about $15 for a whole bag full of wire in differant colors and sizes.

$1,200 sounds like a lot of money. But that's about 1/3 the cost of a similar system from other companies.

I spent last week end building the wiring harness, and re-doing some of the dash wiring. I'm about 1/2 way done. Building this harness is a lot of work. Soldering the wires to the connecter was not difficult, and only took a couple of hours. But keeping everything organized, building in some special connecters, etc, makes it a big deal. It's not just building a harness, it's adapting the new harness to the old components.

I have not yet installed the computer in the car. I need to make some mounting plates to make this fit where I want it to.

It's a lot of work, but so is building a car. I'm not in a rush, and I want to do it right the first time.
