I just cleaned out a mouse nest or maybe it was a red squirrel nest as I found a walnut and a half eaten pine comb in my truck. The critters chewed on some wires. The PO rewired the marker lights and tail lights. The 4 way flasher does not work and my horn does not work. I fixed the blower to the heater. Simply had to reconnect the wire that was chewed in two. There are some other wires that are chewed off. Before I connect them I want to know what the are for.
I studied the schematics but they are in black and white... On the right side under the dash going into a red inline fuse are these wires: white with blue stripe that is chewed off.Others in that group are a think black one, a white with blue stripe and a green with red stripe.
Going into a yellow inline fuse are: a green wire, and a red wire. Both these are chewed off. There is also a red with blue stripe and a black wire.
This is on my 1970 F-350. If you can fill me in it would greatly help my search to fix my problems.
thanks!

Re: 4 way flasher wires

The chart is fairly accurate for most trucks. Take the wire numbers from the diagrams and cross them with the numbers in the chart.
