    94 RS wiring harness question

    Hi I have a 94 R1100RS that continues to run and work well. It has all the options for that year but recently I took off the left side tupperware and found what looks like a wiring harness that has been cut and taped over.

    Everything runs well but out of curiosity does anyone know what this is? Why itís there?

    Has the carbon canister been removed? Someone may have been very thorough while performing that task

    I am too lazy to go pull the side panel off of Big Red but I am pretty sure that same taped lump is on Voni's 1994 (built in March 1993) R1100RS. I think it is a chunk of harness used later on other models like the RT for something - I never wondered what. Note that the earliest R1100RS bikes did not use a Cat Code Plug because they were hard wired, but then later harnesses were designed to route through the Cat Code Plug for different models in different markets. I think BMW was building harnesses for semi-universal fit and didn't always use all of the harness.

    Underneath the tape are all the splices/common points for the harness +/- etc.
    All oilheads have this.

    Yes this makes sense. It does have the canister delete and Iíve also heard that it could be a universal bmw wiring harness. Thank you for the replies!
