Not really worried about the drilling part just worried about the space once everything is put back together. Don't want the wires to interfere with the shifter
any suggestions on how to do this. would want to go through the firewall and have it look clean. prefer to have it look as factory as possibleThe only thing is, what are you going to power and how many amps does it draw.The wires in the existing wire harness are not big enough to handle a lot of amps,so heavier ones would have to be run with an inline fuse of the right size installed at the battery,of course.
