Does anyone know the correct way to wire an ignition switched +12 for cars that are'nt factory equiped, using spdt bosch relay??? I've read it somewhere I just can't relocate it. Any help would be cool!

I wouldn't even use a relay for a deck turn on lead. Just run a wire from the acc wire at the ignition harness to the deck. I would however use a fuse.

Okay, thanks for knowledge. That is the route I have been running for quite some time now. Just curious if there was an ?alternative? and if headunit would benifit. Thanks again!
