    Interchangeable wiring harness

    Hey everyone,

    Finally got back to work on my bike after moving to California....then I fried my wires.
    I'm looking into replacing my wiring harness completely rather than diagnosing which wires were burned and exposed as a result of my stupidity.

    It's a 1980 GS450 S model.

    Has anyone here had experience using the harness from the L or E models to fit the connectors on my bike?

    the two things I never have good luck with...electric work...and plumbing.. I'm really hoping I can fix this myself(with everyones help on here of coarse )

    Well if anyone is interested to know...

    Talked to someone at a local bike shop and they said the harness' are practically the same from 80-81 across the board.

    Found one pretty cheap on ebay that didn't specify the model..we'll see how it works.

        Got a harness from a 1980 E Model on ebay for 20.00!

        Wires seem to be the same color, same connectors, ect. I'm going to put it on this weekend. Hopefully it starts right up!

          Suzuki has been very consistent in air color codes across many year/models. That doesn't mean all the harness are the same. You can probably unwrap both harness's and clean replace connectors on the correct harness using the spare for mainly a wire source. While you are at it make the require charging system mods.

            I bought a complete harness was so that I didn't have open it up!
            Thanks for the reminder to mod the charging system!

            New Harness from the E-Model went in perfectly, wire for wire, every connector and length matched. The only strange part was that the ignition button stopped working. I examined the control and could NOT figure out what was going on with it.
            So I ended up just running a new start button hidden out of the side of the side panel.
            I ran re wired the R/R to go to the positive terminal and ground on the frame.

            EVERYTHING RUNS GREAT!
            System is charging, lights/signals work. Life is good.

            Before I burnt out my wires my battery would never charge. When I looked at the wires they were all corroded and junked. So really this has helped bring something I needed to fix anyways to my attention.

              Congrats, sounds like you got something that was virtually a direct replacement.

                Yesterday, ran it all day no problems. Today, on the road 10 minutes and my speedo and lights go dark. Now the engine turns over but I can't get any life out of it... Any ideas??

                  Okay cool, on first inspection it seemed like the fuse was fine, then I noticed it was burnt at an end. Replaced and good to go. But I think the rectifier might be pushing too much juice. That's a 32v fuse! But it might also be 30 years old

                    Just do a "Quick Test" (link in my signature) and report the results.

                    We can go from there.
