Wiring is easy if you got the user manual and all the correct parts. In my case I got shipped the wrong brackets no user manual and missing parts. I believe they have not sold to many of these so it is still a work in progress. Once I got shipped the right parts from AMP everything was easy. Four wires connect underneath the dash and the module bolts on to the battery easyly. I will post some photos as soon as I get a chance...how easy was the wiring?
