maybe. i know there are taps you can buy that add another terminal in the fuse box... that's how i have my radar detector hardwired. is there a way i can tap into a 12v source without having to share a fuse with several devices. and then how would i hook up 3 or 4 devices to this new source?
I personally wouldnt do a fuse tap. If you want to do it right, Buy some wire, and some of the terminals, and a fuse holder. Wire it directly to the battery with the fuse very close. You can always find a grommet or plug on the firewall to go thru. Once inside, then connect it to the various electronics. You have a dedicated line then, and you wont risk melting the light guage wires in the vehicle harness.
You can also buy an amp wiring kit, they come with everything you should need...and instructions
