Sportster 1200: Little by Little Changes, Part 4

Continuing from converting the handlebar to metric and the switches to metric, which means domesticating it.
How is the difference in turn signal ON/OFF method being controlled?
I only have wiring diagrams for old Sportsters, so they’re not much help…
After poking around, it looks like the turn signal module is controlling it. (See manual) ’91
Good thing it’s not mechanical ★
To switch to a domestic push-cancel, there are two steps:
• CUT the signal coming from the module
• Install a turn signal relay
 

 
Embed the turn signal relay inside the handlebar switch wiring.
It’s a bit pricey, but the Motogadget M-FLASH is the best layout-wise.
 

 
The Sportster really has so little space, it’s a real problem.
 

 
Finally found it… the module. It was inside the fender right in front of the rear tire.
 

 
Finally done ★
Blinking OK! Push-cancel OK! Hehe
Or so I thought…
Huh? There’s a position function? On the Sportster…
So I took it apart again and fiddled around some more until everything was complete.
Checking and double-checking and triple-checking took time.
The first time is rough.
The ETC wiring is also done, and it’s almost finished.
Phew
