Question on wiring my TPMS

1864 Views 6 Replies 5 Participants Last post by  bobf
Thanks for any help on this. I bought a Doran TPMS. Once I figure out the valve stem issue that I posted about, I need to figure out how to wire it in. I'm pretty good at following directions, but haven't done much wiring in my lifetime.

I have a 2012 Ultra Limited and have decided to run the wire from my mounting spot for the TPMS back to beneath my seat where the battery is. The instructions say to connect the red/positive side to a 12-volt positive connection. That's no problem because I figure I can wire it directly to the positive post on the battery.

It says to connect the black/negative wire to a good ground connection. Any ideas what is considered a good ground connection and how to hook it up?

My other option is to connect it to the aux connection which is controlled by my aux switch.

Sorry if this is a dumb question to some of you electrical gurus, but I want to learn more about wiring so any advice helps.

If you hook it to the straight to the battery, it will be powered up all the time. If you hook it to the aux, you will have to switch it on with the aux switch. I would prob hook it to the aux switch to keep it from possibly killing battery. There should be a couple of places under the seat where you can find some grounding points. Should be two posts that has grounds already hooked to it in front of battery tray.

Black to ground ( frame anywhere) . The switch is needed , so it's the best option to use . :thumbsup


:coffee:
And you can buy the harness adapter from you local dealer and it will plug directly into the plug coming from the switch that's under the seat.
Hi, Since its an electrical thread I would like to ask if I am replacing worn wires while bike is apart and now dealing with starter which was wired with stranded thin wire I don't know exact guage but, can I use solid copper wire I have left over from florescent ballast that might be one gauge thicker instead of the stranded? I don't mind buying stranded same gauge but thought the only benefit to stranded is flexibility. Any information is so appreciated. Thanks very much.

Stranded wire is used because the wires MOVE . Use Automotive wire too, NOT house wiring . :)
What he said. Also you can use larger gauge wire just not smaller.
