"wud"? what the fuck does that mean?
Anyways, this sounds like basic electrical work, you might even be able to just get some dude that's good with that sort of shit here on TR to do it cheap for you.
I'd probably be able to do it, but you sound puerto rican. I know that a user on here named Notladstyle (usually hangs out in Audio forums) does some damn good electrical work and will probably be able to help you out for cheaper than a mechanic, which sometimes start labor fees at $99 for just the first hour.
