Switched Live feed on a BMW GS

Where would be convenient to find a switched live feed on a BMW GS 1200?

Need it to operate a relay(or two) for a couple of electrical extras - Sat Nav and flashing lights for marshalling duties.

Ta.

Me, I'd take it from the side light, as it's always live on todays machines. Tis what I've used on both the F8GS's and the F658GS twin.

If you take that feed to energise a relay that then switches in power directly from the battery (via a fuse of course) for the other circuits you want to use, job should be a good un :thumbsup:

I took one from the live wire that feeds the diagnostic plug using a post tap to access the wire. I could go and check which colour it is. BUT, if I was doing it again I would go for either the live wire to the accessory socket below the seat (advantage/disadvantage here would be the circuit stays live for a a minute or two after ignition off) or from the live to the rear light/or the side light as Steve suggests depending on where you want to put the relay. If all its doing is triggering a relay then I am assured from posts on UKGSer that the Canbus is not so sensitive that triggering a relay from a can bus managed circuit will make it throw an error.

What happened to the tick tock thread then. I would never have guessed a GS.

Lutin, I thought you are da man when it comes to electrickery stuff?
I don't know jack about canbus other than in my humble world, it seems an overly complicated way to crack a nut, so can't offer any remotely useful input....
I'm sure if you spark a couple of wires together, it'll point you in the right direction [emoji10]

You, a GS1200? Or one of the blood bikes?

Sorry, should have made it clearer - No, it's not my bike. It's for a mate who's a Blood Bike and Bike Marshal colleague.

Any "Tick, tock" thread will have to be preceded by a "Build a bigger shed" thread. One of my New Year's resolutions.........

I had a good look around the inter-web for this some while ago - but got all confused. Using the accessory socket would be fine and the delayed switch off really would not be a problem. But where is this accessory socket exactly? What does it look like? And can I get a matching plug without it costing a fortune?

Should have made myself clearer in my original post.

So, bigger shed in the new year

When should we expect the Ticking to start? [emoji6]

Is this for the LC?
If so I've wired an accessory socket in using a fuse block.
It stays on for a few secs after the bike shuts down but that's a small negative really for the convenience of using it.

No, it's no the LC - it's a late Oil Head.

Accessory socket on my 2011 GSA is left side below the seat. Find the switch for the seat and forward about 4-5inches mounted into the tool tray. Or look under the seat in the tool tray to find the innards of it and the wires. Its a DIN plug with a black cap and its well tucked in so you will probably need to get well down to spot it the first time.

Rather than use multiple relays ,triggered by the same ignition feed, use a 5 output module from marksmotorcycleparts.co.uk It allows 4 x5amp and 1x2amp outputs, with each output protected by a self repairing fuse. £30 from memory.

Thanks for that. I'll have a shufty at Fergal's bike the next chance I get.

Any idea what colours the wires are entering the connector?
