Wire Diagram / GS500F - 06 Jun 09, 2008This couldn't have come at a better time. I'm putting a 04 motor and harness in my 91. I know the two are very similar but my old harness is caked with 17 years or dirt and road grime so it's hard to tell what's what. Clear-Com Headset Pinout | ControlBooth May 22, 2014I basically soldered the 3 stereo plug to onto pin3 and pin4 of the clear com headset cable. It works somewhat. I can listen to the clear com conversation normally if nothing is playing via the 3.5 adapter (ie ipod etc.) or vice versa, I can not hear both. It seems as though the 3 cancels out the clear com audio. Any suggestions. Thanks DM
