I just installed my brake controller tonight and came across this site to prepare. Super easy... just be careful if you plug it in and try to snake the wires into the dash and hit metal, the wires are HOT! Sparks happen. I suggest splicing and wiring before hooking it up to the connector under the dash. Either way, here is the link: http://www.randpcarriages.com/tech/n...kecontrol.html
