Default Q: 2006 Wide Glide Turn Signal Sense Wiring

The previous owner changed the front turn signal units.
When he did it, he didn't realize that the extra blue wire was for computer sensing and he didn't reconnect those wires.
Now I am getting codes that the trun signal sensor is not working.
Can someone tell me:
Does the sense wire connect to the hot turn signal wire or does it connect to the return (ground) wire.

On my bike the blue wire is for the running lights. I unhooked mine and don't have a problem and never got any codes because of it.

Maybe the blue wire in the front is for running lights, but it is integral to the small sheathed wires that go to the turn signals on my bike.
Maybe the sense wires on the back signal units, if the front wire is for running lights.

Unless they made a change from 05 to 06, which I have not found to be the case on wiring, the blue wire on the rear lights is the running light, just as it is on the front.

Here is a simplified wiring diagram I made. The sensor for auto cancel is in the speed sensor, it senses change in speed to cancel the signals from what I have been able to figure out. Found this when I went to the digital gauge, auto cancel did not work without the speed sensor wire connection from the ECM.
