Red wires
Does it matter if the hot wires on the coils are hot with the key on or key off? Also, does it matter if the hot and ground for the ecu go straight to the battery or can they be switched as well.

The wries that go to the coils need to be switched, otherwise you will have a constant power draw that will drag the battery down when the car is off.
The thick red and black need to be connected directly to a constant source of +12V and ground. I'm sure you can switch the big +12V if you want, but why?

I thought that was the way its suppose to go because I would think the ecu needs a constant 12v to retain its memory. I already have everything else wired, just the main 12v source is left to hook up and its running.

I have a question. I have an lt-8s with the ecu adapter. I haven't installed it yet. Whats the proper way to install it? I was assuming to just plug it on and go. But i saw a post here where some1 said (maybe you aaron) that you shouldn't use the stock ecu power supply wire to power the microtech..cuz it will keep blowing the 15A engine fuse? If this is the case..what the correct procedure?

if you have the ecu adapter you can plug and go.

Either way that wiring is old and of thin gauge. The Microtech's thick power wire should be directly connected to 12V at the battery because not only does it power the Microtech, but also supplies power to the fuel injectors (about 4A each for low impedance).
If that's what you believe, then who am I to argue? But if I received a car from a shop with the coils wired to constant 12V, I'd be demanding a refund.

Jon from microtech said to run it straight to the battery, which to me says no relay. Someone correct me if I'm wrong. The only thing you need a relay for is the fuel pump.

What he said. The thick red and black wires go to the battery and ground, through a fuse of course.
The pink wire then goes to +12V IGN, which I generally tap from the black/yellow wire at the trailing coil.
The wiring diagrams are in the back of the manual, and at the Microtech website. If you do not have a manual, you can download one from the website as well as as wiring diagrams for popular applications.

I ran the pink wire to the black/yellow wire connector on the passenger side of the engine bay. I ran the pos coil wire to the trailing black/yellow wire. That way both are switched to the key. Still hot and ground(earth) are to the battery.
Where have some of you put the hand controller in the car? I'm thinking the dash pocket, but I also want to be able to watch it sometimes.
