I need to wire up my wideband and boost controller and need a good positive inside my car that gets power only when the ignition is on. I have a 92 prelude H23. What wires do most people tap into for this car for power/ground? Im not too good at reading the electrical diagrams on the manual I have. Thanks.

 

The White with black strip wire is the ACC wire this wire would be the best wire for tapping into.

 

I would just use the cig wire unless you smoke or use it for another device.
