Near Intersection of I-35 & I-90 Southern Mn. | Thanks for the replies. None of the drawings or other Internet searches seems to match my radio. If I proceed I plan on assuming the orange wires are for speakers and thr red for power with the black being ground. I don't know the purpose of the brown wires.
It might be safer to open up the 7700 tractor to reverse engineer what I did when I installed the other radio but my nephew now owns the tractor and it is used for livestock everyday.
