Near Intersection of I-35 & I-90 Southern Mn. | Thanks again. The diagram seems to agree with my thinking. The tractor and truck only have one pair of speakers so one orange pair goes to each. The color coding on the switched power, constant power and ground make sense. One brown was probably for lights which I'm not concerned about.
As far as the fuse, it may have stayed with the 7700 or possibly was fused through the fuse panel. An inline fuse would be a good idea. |
