relay in harness?

[Leedogg]

OK put my harness together last night.

It has this relay on it- but the instruction made no mention of it. What is it for?

That should be the relay that retains the turn signal/hazard "clicking noise." Same concept as the stock turn signal relay click but for some reason when you swap headunits to aftermarket it doesn't work anymore which is what that is for.

That makes sense. I was stressing that I didn't know what to hook to it.

Thanks!

Yes, the relay is for turn signal. I am also doing similar set up. Do you by any chance got usb-can cable for update?
