Fun with wires

This is a cross post, and so the text will be a bit weird

I'm wiring up an aux-fuse block on a GS500.

I have a relay setup, taking power directly from the battery. The switch is by default open.

What I am looking for is an ignition switched power source. I only need a few milli-volts to close the switch on the relay (which will provide power directly from the battery to the aux fuse block).

On the CBR I tapped the license plate light. This GS uses the day time running lights of brake housing to light the plate. so I could tap that. That'd work, but I have avoided doing that... if I have to have a light fail I don't mind it being the license plate light, but I don't want to loose the brake light!

Does the GS 500 have an auxiliary power lead? On some bikes there is a lead near the front which would be the day time running lights/park lights when required (i.e. Euro).

Found one - the horn is always hot, and since I only needed a few milli-volts it was perfect. (Hot when the ignition is on, not hot when the bike is key'ed off... which is exactly what I wanted to trip my relay)

I've got a photo series of tapping that for switched power, making my relay, and running the cables for a switched 10amp 12volt circuit... perfect for any/all auxiliary devices you want to run.

12v 30amp relay was ~$12

3 colours of wire, ~$20 with miles of spare left (I had actually brought it for a different project

3 - two pin SAE trailer style plugs @ $4 a pop

All told doing this, and the other wiring probably took 2 hours real work, and probably 4 thinking it through.

NIce looking GS .. (still prefer the nekkid ones though)

 

Are you worth more when you are thinking or when you are working? Good job, looks very thorough.
