Hey cat guys, im dealing with a 988G, No horn (tested switch and all is good), but when the lights are on the horns sometimes work on their own, so customer has ran w/ horns disconnected. Also radio in cab is intermittently not working (currently not). I would definitely appreciate a wiring diagram if possible. Thanks
Loads of different 988Gs. A Serial Number would help. Not sure if the horn power comes via one of the ECMs or not. It wouldn't surprise me TBH.
