If you're alarm has an engine kill relay, you will need to tap your turbo timer's ign power around it.

Clutch switch does not matter since the car will already be running when your turbo timer keeps it going.

I zip tied my wideband controller around my shifter cables underneith the center console, near the firewall (don't crank down on the zip ties, you wouldn't want it to effect your shifting, lol). You'll have to extend all of the wires on the harness regardless (unless they changed the harness length on the newer Zeitronix controllers w/ the turbo timer function).

P.S. I'd solder all your WB controller connections, and make sure you have a solid ground at the same place your engine managment is gounded.
