/facepalm

and ride more apparently... or i'd remember that the dash indicator blinks with the turn signals. I think I'll just leave this thread alone now as it's showing my brain has melted too much in the decade since high school [laugh]

Ok, so if I wire the indicator LED in parallel and ground it where it is now, wouldn't it blink constantly?

Also, there is one slight dilemma I've discovered looking at the factory wiring schematic. I'm connecting the entire dash through a harness (or at least trying to) into the factory dash wiring. That's all well and good except that the neutral pole on the signal switch goes straight to ground, not to the dash. I obviously COULD find it, snip it and patch into my harness from there, but can anyone think of a way to run this circuit differently that would allow me to not have to patch into the factory wiring?

Anyway to upload a PDF? I'll take a screen shot of the factory wiring.

What do you mean 'neutral pole'?

Are you saying they ground everything through the switch and you need a ground at the dash?

There is the factory wiring. The center pole of the switch never goes to the dash other than through the ground circuit which I can't feed a relay into...

What if you run the relay ground through the switch instead of power?

My apologies... not following you. The relay ground would still have to get to that center pole outside the harness.

No apology necessary. You have the advantage of having a complete wiring diagram.

If the off position of the switch is grounded and goes to the dash why does it have to go outside the harness?

Are you trying to use the relay in the original cluster?

Pin 22 is the ground for the dash, which goes into the chassis ground circuit. So if I run the relay negative wire into that pin I run power directly into the ground circuit as it is currently sketched out. That's how I'm reading it at least.

The reason I'm trying to keep everything in the harness is that I'm doing my best to keep the factory wiring unmolested. First and foremost just to see if I can do it because it would be a clean solution, and secondly to prevent much damage to resale if I ever get stupid and sell the bike. If need be, I can always hack the wire coming off the center pole of the switch and go with the circuit as drawn, but I'm trying to see if there is another way if possible. Not much more than a mental exercise and practice with this stuff.

Does the off position of the switch run to that same pin?

If I'm reading the diagram correctly in Reply #18 and understanding the operation of the switch, then the "off position" is just open switch. Left position grounds the left circuit through the switch, right position grounds the right, center position, no flow.

Eh screw it, I'm going to patch into the wire. No reason to beat my head against the wall if there is a simple and obvious solution.

Next question then... anyone know where the switch harness is on the bike? I can obviously trace it when I get home but if someone knows I can start noodling where to route the wire.

Does the relay you want to use have a ground?

If so, you should be able to feed power to the relay through any live switched pin from the factory connector and connect the ground from the relay to pin 22 and it should work.

That's the way I see it anyway.

Pin 22 goes to common ground, not solely the switch though, am I wrong in thinking that would only power the relay and the indicator while feeding power into the ground circuit? The relay I'm using is a simple two lead, power in, power out.

I may have oversimplified the factory schematic, the wire running between the switch center and Pin 22 is the ground circuit for a number of components.

I would be pretty thrilled if it was that easy though. That was where my brain was at first until I looked at the factory wiring.

You need a relay with a separate ground to do it the way I'm suggesting, and I bet the factory relay had a ground connection.

Ground is ground...all power flows through a device to ground. As long as power doesn't back feed and power another component it doesn't matter.

Agreed that ground is ground... I'm just curious how doing anything with Pin 22 without wiring directly to the center pole of the switch will get power back out to the turn signals I guess. I would think it would just immediately ground out since Pin 22 is the dash ground.

I drew up a schematic that patches into the switch center pole. Any issues you see?

It will work that way as long as you aren't using pin 22 on the harness.

The way I read the switch diagram is that pin 22 is the center post and is ground. Moving the lever on the switch completes the circuit.

Like I said, I'm frequently wrong.
