electrical question
so I finally decided to put a speedometer on my bike now that I am active duty. It hasnt had a speedo on it in the 5 years I owned it before, the guy who owned it before took it all off. Anyways as I was wiring everything into my aftermarket speedo, I realized that the speedo only has one light for the directionals but the factory wiring harness has two sets of wires for the indicator lights since the original cluster was seperate for both left and right. my question is how can I combine the wiring so that when either of the signals are engaged it shows up on my new cluster but they dont power each other causing both left and right to blink??

You could power the indicator light from both t/s wires but you would need to install diodes on both wires to prevent backfeeding the other wire. Or you could install 2 relays, one powered from each wire and have both relays switch the indicator light on and off.

Are you saying the speedo encloses indicator lights for turn signals? Each direction or just one light? What about oil, neutral, and beam?
My 91 has four indicator lights outside the speedo, with two wires to each. One turn signal light that flashes when either signal activated, neutral, oil, and beam fill the other holes. I'm guessing yours would be very similar, no?
Does the 92 model have 5 indicator lights, right and left indicators plus the other three?
Maybe you are looking at the wires that go to the front turn signals? Those have two wires per side for the front lights.
Call the manufacturer of the speedo and ask them? They may have heard of this before and have a fix.
