my RD turns much better to the right then it does to the left, and it does got floats on the front, is there anything to do about that

If it still has the black plastic plug on the end of the harness the plug will be lettered A-F F is ign and A is battery. Here is the only diagram I could find. Hope it helps

that does help, thanks

i bought an 88 mack rd690 dump that had a radio in it at one time but once i got it, it wasnt there anymore, the wires and plugs are still there, i got a pioneer radio from my buddys junk yard that came out of a hyundai, i know i got to cut off the hyundai plug but the pioneer had 10 wires and the mack has 5, does anyone know what those five wires are for, like what color does what?
