Universal Control Switches

Hello all.

I bought a set of control switches off eBay which have on/side/dipped switch for the headlight and a high beam flasher as extra. I've managed to get all the lights functioning as they should. The issue I have is that the starter motor will attempt to turn over but I'm getting no spark at all.

The right side switch has a slightly different set up to the original ones, and I can't seem to figure out which wire should go where.

Has anybody fitted such after market switches to the Rebel? How did you figure it out?

A link to the switches are here but it doesn't show any wiring diagram of any sort. I have an extra Brown and Brown/White wire. Even if there's nothing going to the Brown/Red wire that goes to the fuse box for the lights, the lights still work. Perhaps the switch bypasses the fuse box somehow. I'm not sure.

Rebels are different over the years with the electrical system. It helps to state what year your Rebel is.

The item you listed is advertised for Gen 2, you have a Gen 1, but if you are cleaver with wiring you can make it work.
It has a right side slider switch for lights off, park, park+ headlight, I would not use that, the headlight and tail/turn lights are on different fuses and if that switch is bridging the 2 circuits it could result in cooking a wire and catching the bike on fire. you would need to dig into it to see if that switch maintains 2 separate circuits or bridges them.

You will need to look carefully at the wiring diagrams for both Gen 1 and Gen 2 to suss out what's what, and use a multimeter on the purchased items to identify all the leads and what they do.
the ebay page does not include a spec sheet, its not clear but I'd guess you have to crack open the left control to connect the enricher cable, the pictures do not show one.


No spark might be the B/W (black/white) wire from the CDI to the run/stop switch wired wrong. From the diagram I'm looking at, key in off or park, or run/stop in stop connects B/W from the CDI to ground to kill the spark.

Rebel ignition system is totally independent of electrical/charge system..
Attempting to turn over?? is it or isn't it?
faster the crank faster the start.. slow crank Low battery imho

1st generation 85-87 Rebel electrical wiring is somewhat different than 2nd gen 96-2016. Most Rebel owners are unfamiliar with 1st gen peculiarities. You will find 1st generation Rebel files on my google drive that may Help your wiring woes..

You will have to figure out the switch pin-out (which switch wire does what) and match to wire harness..
Only reference I can relate to is the bikes harness color code.. Yes you may have a spare wire from aftermarket parts.. Consider contacting the seller.

The 1996-2009 diagram you posted is exactly the same as the 1985 diagram in the haynes manual.

Did the 1996-2009 right control switch have a 9-pin connector? The item description claims it's plug and play, but as far as I was aware, the Honda Rebel never came with a switch to turn head/tail light off, at least I've never seen such a switch in any wiring diagram for any model Honda Rebel.

I'd say your Haynes diagram is Wrong ..
85-87 diagram comes from honda shop repair manual I scanned and colorized wire runs..
Appears the 2nd gen rebel has an 8 wire pin-out where the 85-87 is 9 wires..
additional Green harness wire of 1st gen switch provides ground to starter solenoid via clutch lever switch, wiring diagram indicates it doesn't interact with any internal switch contacts..

never had a problem with switches other than contacts needing to be cleaned.. Thus I have only been into junction box to add diodes for LED turn signals.

on another note @kryton is correct, grounding kill switch circuit kills the cdi output.. during run that circuit should be open..

as a side note the 1st gen ignition switch has a third "Park" position that grounds the same Bl/W cdi wire yet energizes tail light.. 2nd gen Rebel Ignition switch has no P park position, on off that's it.
makes finding replacement 1st gen 6 wire Ign switch a pain.. after 30+ years the plastic housing becomes brittle, known for breaking..

as a final P.P.S. No the Rebel has no headlight off position.. Headlight circuit is disengaged when start button pressed so it isn't drawing power while starter is being energized..

I think that might be the problem. New switch has a green wire and yellow/red wire coming from the starter button, where as the original has a black wire and yellow/red wire. Right now I'm grounding that green wire, so it should actually be connected to the original black wire? But then I have a 2 other black wires, one coming from brake switch and one coming from light switch. I may have to mess around with it and just see what works.

Switch pin-out colors reflect wire harness colors..
sometimes wires coming out of switches don't match loom/harness colors..
visual of internal connections, all oem switches may help
