compass location

Prostar, in the fuse/breaker panel in front of the passenger seat. It is about 3/4" thick, by about 2" wide, held in with two screws and has a 4-wire electrical connector going to it. Usually black in colour and the electrical connector is white. I don't think it can be mounted backwards due to it's shape. They get corrupted all the time and need recalibration. There is a simple procedure in the operators manual for this.

 

LOL, I had a 50/50 chance of getting the right truck the first time, wrong again! The sensor is basically in the same location. It is right above the fuse/breakers, kinda tucked up there. The sensor should have 3 wires plugged into it. They should be 18 gauge, green in colour and numbered 41H, 41J and 41G.

Here is link to the supplier website with some troubleshooting, recalibration and some other info;
