I think I have read every old post regarding the Russ Thompson turn signals with Ron Francis harness but I still don't understand why there is so much duplication and extra wiring. I got my MK4 complete kit back in March and I am just starting to dig into the wiring. The Ron Francis wiring diagram and harness seems quite complete with labeled wires, relays, flasher,etc. . The RF wiring diagram shows three wires plugged into the supplies three position toggle switch for the turn signals. If I plan to use the Russ Thompson 3 wire turn signals, why can't I just replace the 3 wire toggle switch with the with the RT unit? The other two red wires on the RT unit that come from the stem button I plan to use for the horn. I spoke to Russ today about this and thinks it should work. The high/low beam and flasher toggle functions would stay as originally supplied. Has anyone tried this??
