Wiring on a 1666

Hi folks, I am in process to replace the e-unit on my 1666. The e-unit is in but somewhere along the line I have an extra wire. There is a wire that goes to the headlight that come down and “Y” off. One side goes into the bottom of the motor area and the other end of the “Y” is what is diconnected. Anyone know where it goes?

I would send a picture but I am not sure this forum allows that to happen.

Thanks,

Bob

I got it. Just a short panic.
