Plan on splicing the wires that go inside the passenger compartment into the wires coming out of the firewall next week. I go back to work tomorrow and won't have a chance to work on it till next tues. I was going to spend a little time on it today but my buddy came up with tickets to the Dallas Stars game. Gotta hate diversions. LOL So, my baby sits till next week after I get off of work from the rig. Be back soon.
