Can't tell by the pic what the crimped wires are or go to can you explain what they go to.
You do have the circuit breaker which is the gray plastic block in the upper left. I also notice what looks to be a fuse holder with a black wire. Does the black wire go to the circuit breaker or something else. I see the top wire on the breaker is red and looks like it goes to the battery, is that the case.
The front of your electronics box/tray looks like it is missing a bolt. I don't have a Mastiff but a friend of mine does. When we did the fuse/circuit breaker upgrade his tray lloked the same and the 2 rear bolts were loose and ready to come out. We just tightened them up.
Got more info ?:up:
Thanks V
