I just bought a 96 F250 for a work truck and have a prodigy brake controller to put in it. My question is does it have a plug in under the dash for a wiring harness like the newer trucks do?? My new truck had a wiring harness with it that you plugged in under the dash then connected the right wires to the ones on the brake controller. Thanks in advance for your help. Also anyone know where i can find some towing mirrors for the same truck, it has the small chrome power mirrors and is going to be towing a 8' wide enclosed trailer, can't see crap?? Thanks.
