Switched power lead rear of 07RT

mikegalbicka

Back in the saddle again
I added a set of Skene Design P3 LED lights to the rear of my 07RT and followed these install instructions which used the green/white alarm wire to power the red controller wire. Lights look and work great. The alarm still works BUT the flashing turn signal indicators and dash board light used by the alarm do not work any more. They come back fine if I remove the red controller wire. Jerry Skene replied "It could be that your alarm is a bit more sensitive to the extra current draw. Try running a wire up to the blue/white wire in the headlight connector. This powers the small parking light in the headlight." That is going to be a pain. Any better ideas?
 
There should be a two conductor plug under the passenger seat, left rear, intended for an optional Powerlet socket. You should find switched +12V there on the red/green wire. This is the same circuit as the front socket and GPS, so it may cause the lights to stay on for a short time after you shut down the bike, or cause them to light if you use the socket for a battery tender.

Some say the blue/green wire at the diagnostic connector is switched power, some say don't touch it. :dunno

I have successfully used this wire to power LED lighting in my top box on my '08 RT with no issues. As to the aforementioned shutoff delay, I call it a 'feature'.
 
Thanks for the info guys. I plug my Optimate 4 CanBus battery tender in the rear powerlet so I guess that would cycle the lights quite a bit! Will move it to the front and give this a shot for now.

Yes it is - and the people worried about touching it haven't looked at a wiring diagram of the bike. It works fine for switching relay power for things like a FuzeBlock.. (and the GS-911 still works..)

Just used it on an 05 GS this morning for a buddies running light relay trigger.

Have used it since 2006 on many bikes to power relays and or aux running light modules. I didn't care for the lights to be on after I walk away...even for a few seconds as folks always told me about them.
 
Thanks all for the useful info. Since it appears safe to use the blue/green wire at the diagnostic connector I may try and use that instead so I can keep the battery tender in the rear powerlet and not have to worry about the ZFE cutting the lights off. Haven't noticed the connector previously but it should be easy enough to find. Hexcode site shows it to be a large round one.
 
I found the diagnostic connector under the front seat but that wire is a little harder to get to and I only had a little time tonight to play with it. I hooked it up to the rear powerlet and was surprised to find that when plugging the battery tender into the front powerlet the rear powerlet energized as well. Didn't expect that. I figured they were on separate circuits. That means I would have to go direct to battery with the tender instead. That is actually preferred by most I think so will sleep on it and decide what I want to do. With nothing plugged into a powerlet the lights went off 60 seconds after key off consistently.
