    Ok guys. I have a 2001 DC v6 and when I got the truck it was wired up for a trailer. It has the trailer pigtail plug right behind the bumper. I don't have juice coming from the plug below my bumper and I think it's called the male plug. So I'm trying to trace where my problem is. First trace is to look at the fuse and make sure it's OK. The diagram doesn't show a trailer fuse so thought one of you may know which one runs the trailer lights. Thanks Rick

    Did you buy the truck new? Are you certain its a factory install? have you taken the taillight out?

    Not really sure if it came from Factory. I bought it second hand. Rick

    The tacomas require a convertor box (modulite) to convert the wiring from a 3 wire system ( seperate turn signals) to a 2 wire system (brake and turns combined). These convertors are notorious for going bad and causing the same issues your are having. Crawl under the truck or in the taillight area and look for the box.

    Chances are it has gone bad and needs to be replaced.
