    Sorry if this is posted somewhere and I missed it.

    2009 Touring.

    I need the wiring harness schematic for the turn indicators. Front and rear. Preferably a place on the harness where I can effect both the front and the rear.

    If it helps, I'm wanting to change out the lamps for LED bulbs. So I'm hoping to find a place in the harness where I can install the required resistors and mount them to metal. Any info anyone can share on a good location for that metal mounting would be wonderful.

    Why don't you just replace Turn Signal Flasher Relay? New ones can handle both LED bulbs and the old incandescent bulb, should you ever need to revert to those.

    The Turn Signal Flasher Relay is located in the cabin behind the dash and to the left of the steering column.

    Thank you very much. I've had issues with specialty flasher relays in other vehicles but these relays from diode dynamics seem tailor made for prii. I appreciate the input. Now I can focus on other modifications.

    So a new problem... I found diode dynamics flasher relay for LED and Standard lights...

    But the one every website says should fit doesn't seem to. Everywhere I read says it's a cf18 relay. And sure enough, the one in my dash is. But the one I ordered has long locking tabs and the one in the dash has short ones...

    What gives? Everywhere I look says I have the wrong flasher in my dash and yet nothing else fits. I can't seem to find the correct flasher relay. The first picture is what's in my dash. The second is what everyone seems to think belongs there. Any help finding the correct one would be appreciated.

    If I remember correctly, you just cut the tabs down to match your existing relay, then it slots right in.

    I am not sure why they supply it like that if it is supposed to be a direct replacement.
