Ok...I wanted to setup my 01 rig for towing. I bought OEM toyota stuff and I installed the fused harness on my battery and hooked it up to the connection next to the battery in the fender, second I installed the trailer harness behind the license plate. What do I have to do next? I thought it would all work, but I get nothing. What am I missing, did I not plug something in? This is driving me nuts. Oh I am just doing a basic flat 4 pig tail wiring, nothing special.
