Just got the motorcycle cable and bracket. The bracket is a flat back mounting type, so the tilt no longer works. The harness is spliced about three inches away from the unit connector, two wire sets. One six inch with speaker jack, and then the fused power. At the end of the fused power cabe are two remaining wires cut. They are dead in the water, probably the original speaker wires, do not connect to any points on the unit connector. Thought they might be the speedo and reverse wires I need for the 2650 hook up. Seems like I might have to buy an original cable and splice it up. Lets get this mounting thing straightened out, spring is coming!
