Hello again...If I keep posting eventually someone might read this that could help me lol...anyway I have located the rear harness schematics from the 2018 and the 2012 rear harness for a touring bike. See pic. I was wondering if I could get your advice if I were to cut the connector for the 2012 that connects to the bike and reconnect it to the harness for the 2018 that goes to the control/3rd light module. What color wires would you connect? I might try re-pinning the connector also.

 

 

I see the connector for the 2018 reads 6 through 1 left to right yet the 2012 reads 1 through 6 left to right...that kind of confuses me lol

 

If I re-pin the 2018 connector that connects to the main harness I am thinking this is what I do...please confirm...PLEASE

POSITION 1 - SWAP RED/YELLOW STRIPE FOR BLUE/BROWN STRIPE

POSITION 2 - SWAP BLUE/BROWN STRIPE FOR RED/YELLOW STRIPE

POSITION 3 - SWAP BLUE FOR BLUE/VIOLET STRIPE

POSITION 4 - SWAP BLUE/RED STRIPE FOR BLACK

POSITION 5 - SWAP BLUE/VIOLET STRIPE FOR BLUE/RED STRIPE

POSITION 6 - SWAP BLACK FOR BLUE

Thank you very much for any help you can give me!

 

If i solder the wires I am thinking...

2012 ORANGE/WHITE STRIPE to 2018 RED/YELLOW STRIPE

2012 BLACK to 2018 BLACK

2012 BLUE to 2018 BLUE

2012 RED/YELLOW STRIPE to 2018 BLUE/RED STRIPE

2012 VIOLET to 2018 BLUE/VIOLET STRIPE

2012 BROWN to 2018 BLUE/BROWN STRIPE

 

not sure if anyone is reading these lol. but i repinned according to what I wrote above and had everything working but brake lights. I then switched the red/yel position with the blue/red position with no change. all lights working left turn, right turn, taillights, and 3rd light but no brake... or maybe brake is on all the time idk... please help!

 

I put everything back to this arrangement above... if the tail lights filament in the bulb is the opposite one than the turn signal filament then everything is working exactly correct except no brake lights...i checked fusses and relays and no change...PLEASE HELP

 

can anyone give me some advice or steer me to someone that can?

 

I have no specific knowledge of your issue but wondering aloud that there were logic/architecture changes in 2014 and later for the ecm and it may be possible its not as simple as wiring up newer/older lights to newer/older bikes.

 

I wonder that same thing. I checked voltage at male plug on bike this morning and everything seems right. I'm going to reconnect 2018 harness tonight and check voltage at other end of harness. other then that I'm out of ideas.
