Passenger side was a pita to get out.
Even getting to the plug saw a pita.
Looking for a wire harness extension.
I did a search, but the plug is different, or the color is different.
Does the color make a difference???
Anyone know where I might get the correct one???

 

If you can't find the extension then you can cut the wire and add wire by yourself. Make sure to use heat shrink tubing and solder the connections. It should work the way it is if it came from the factory that way.

 

Can't get to the plug.
It's so high, the exhaust is in the way, and no space to work.
Extension plug would be the easiest way.
