How do I test for shorts? My ground is the same as the old unit but I'll try a different spot. My yellow constant is hooked to the BATT terminal on the fuse box, red ignition is hooked to the ACC terminal on the fuse box, is this ok? Think I read on here someone else used the same.
This may be a dumb question, but does the constant mean I could power on the unit without turning the key in the ignition? I don't think it does
