Need a wiring diagram for my 2001 F350I bought it used and the previous owners have all these extra wires running thru the box to hook up cb radio, extra lights and other things that have been removed. The truck keeps blowing fuses. Would like to solve this problem but I dont know how without a diagram

You seem to have a handle on the problem .A wiring diagram will not indicate the location of the aux circuits. Any non original looking wiring should be disconnected from it's connecting point ie; tail lights to aux lights are usually a short distance from original wiring. CB radios are two core non original and easily from battery or fuse box. Don't go mad on the disconnect but take a long look at whats not the original fitment. let's know how you get on and the blowing fuses thing . Good luck
