Where'd you hook up the 12+ve?
I am just wondering where you guys hooked up your 12+ve on your car. I was think that i would to it where the old coil got its power, but i am unsure if that will be dead or not . Could you guys please help me.

connected mine to switch labeled ignition on custom dash. this was then fed from battery disconnect switch to custom fuse panel. I don't think this is what you wanted, but you asked twice. best bet use a simple test light and find a 12VDC feed from the ignition switch that is always hot even during start mode, if this is a street car application and the stock ignition key switch is to be retained. then run wire to coils. should take 5-10 minutes from start to finish.

where the stock computer went i wired it into a blk and yellow wire. If you have a turbo timer, make sure the two are the same if not then it won't work. turn the car off and let the timer run down, and check for power. IF the wire you use doesn't stay positive during cranking. It'll never start. Learned this the hard way.

Yes, I believe it can, though I've never done it myself.
I believe it uses one of the auxiliary outputs to energize a relay that provides 12volt power to the ECU and ignition system when it's closed. When the key is turned on, the ECU, ignition sysetm, etc is powered, and the ECU will close the relay, which provides a secondary path for battery power to power the ECU, fuel pump, and ignition system. When you turn off the ignition key, the switched 12 volt source to the ECU, ignition, etc goes away. BUT, the turbo-timer relay is still held closed by the ECU, which provides power to keep the engine running. After a pre-programmed time elapses, the ECU opens the relay, which then kills the ECU, fuel pump, and ignition system, thus stopping the engine and rendering the vehicle un-startable without the key. You can wire a SPST switch in line with the primary circuit of the relay to enable/disable the timer without getting into the software. You could also wire a pushbutton switch to open the relay primary circuit momentarily, which releases the relay and will stop the engine (emergency kill switch?)
Let me know if you have questions. I've got answers.
