GTR main harness routing.
« on: October 14, 2017, 06:19:00 PM »
Having made the mistake of not taking photos :( of how the wiring harness on a GTR is routed on the frame, I'm appealing to the Forum for help. Anyone have photos of how it's routed, especially which side of the frame neck the harness goes around? Thanks in advance!

         Sorry, can't post a photo at the moment, sure someone will.

         The main harness runs to the left side of the top frame tube, sitting on top of the left coil bracket.
    At the front end it drops down across the back of the horn where it picks up the ignition switch connections and then loops between the front down tubes and under the bottom of the triple tree to enter the smaller bottom hole in the headlamp bucket.

   The back end goes up over the groove where the top tube meets the seat tube, then down under bracket that holds the tank rear bolt. It comes out through the large oval hole at the top of the battery holder and into the abyss !! above the toolbox. Try to route the connections near the rectifier as direct as posible to their matching leads coming in from the alternator, rear brake, battery etc. Untwist any crossed up leads and thread them through neatly, keeping them clear of the rectifier where possible. This avoids the birds nest you usually see and makes working on them much easier in the future.
 Same in the headlight, try to move the wires to where they meet the wires comimg in from larger grommet and the head light unit. Just makes it a lot easier to connect everything correctly, if you are not having to thread wires through a birds nest.
         Hope this makes sense,  Brian.

Hi Ken,

The three photos attached, from my rusty but un-touched GTR, will help you I'm sure.

Best Regards,

Thanks for the help BRT GTR and czmiike! I'll be putting on the new harness in a day or two.
