I sure hope so...I wired up my turbo timer to the ignition wires (ACC, etc)
BUT there was a bad ground for the turbo timer, so when I powered it - my system got fried and the gauge backlights, radio, cigarette lighter and parking lights didnt work. Then after that, I d/c the turbo timer and to try it out, replaced the fuse to the radio and then with a turn of the key, the radio worked, so Im hoping that since the radio worked after just replacing the fuse, that that means the main relay isnt shot.
