From a wrecker, I picked up a cheap towbar today for a '99 camry wagon. But when I got there, I found they'd just lopped off the harness wires, so now I have to wire it in from scratch. I just want to pull a utility trailer, nothing more. I can't find any t-connector kits. I do have a Haynes manual with a wiring diagram. But I'm reluctant to splice in without any further guidance. Can anybody offer any advice or resources?
