Gentlemen,
I bought a custom Speedo and Tach from Dime City Cycles because I'm sick of looking at the monstrosity of an instrument cluster I have on my '81 CB750F.
Looks easy enough to wire, the speedo included a wiring diagram. But its a LED backlit speedo that only has one connection for power to the backlight. The wiring diagram in the owner's manual for the bike shows it has power supplied to two lights for the speedo, two lights for the tach, and one light for the odometer. So the instrument cluster has 5 total power wire for backlights.
So what the heck do I do? Do I use just one of the five positive wires to the one power wire on the new speedo and tape off the rest of them? And then same for the tach? So I'd be using 2 of the total 5 wires, one to power the backlight of the speedo and one to power the backlight of the tach, then tape off the other 3 power wire and their negatives?
Also, the speedo has one indicator light on it for turn signals. But the current inst cluster has individual right and left turn signal indicators. I assume that i wire both the right and left turn signal indicator positive wires to the one individual turn signal indicator on the new speedo?
Here is the pic of the wiring diagram of the new speedo. I can take a pic of the wiring diagram in the owner's manual of the bike too if that helps.
Thanks from Chicago
