I am about to install a greddy profec B into my 90TII. Where is the best/easiest location to get the required switched 12v power? Thanks.

Cig lighter?

 

I used what are called "piggy backs" they plug into your fuse block, and allow you to plug that fuse back in. Then they then provide you a spade connection for additional wiring. Only thing that sucks is, cant put the fuse cover back on.

I dunno myself. My friend hooked mine up to some radio power wire and now mine only comes on with the lights off. If I turn the lights on my BC turns off I'll fix it once I get my car back on the road though

 

How about the radio IGN +12v?

Either that or just hook it up to the accessory relay up in the engine compartment.

 

There are sooo many places to chose from. The fuse box, ECU, CPU, ignition switch, indicator switch, wiper switch, warning lights, stereo, cig lighter, etc. Just get a circuit tester or multimeter and probe the wires until you find a wire that's hot with the ingition on and dead when it's not. It's that easy. Wiring diagrams (Haynes or FSM) make this even easier.

 

Thanks for the replies everyone. I'll probably go with either the stereo or cig lighter. BTW: When setting the pins on the back of the profec B. Should I even waste my time NOT setting for the overboost condition? Do our cars typically have the problem and need it switched to this setting anyway?

 

I just crimp a spade onto the end of the wire and press that in with a bigger fuse (be sure to get the proper side of the fuse so it will blow incase anything happens). Cover fits and everything
