Can anyone send me a copy of the side light wiring diagram for an 08 Toyota Highlander?

It keeps blowing the 15A fuse under the dash. There does not appear to be a short, but I need to know what is in the circuit, relay locations etc.

Thanks guys

if you test the wires at the light and they all have continuity back to ground then you have a short. only one should have continuity. have you tested them yet?

It looks like there was a uhaul light converter inside the back wheel well. It looks OK, but I think the way it is wired it is just drawing too much current from the light circuit. I'm using an 07 wiring schematic which I assume will be the same other than the actual wire colors.

If you look at the toyota hitch light plugin, it is behind the dash on the drivers side and has a separate fuse for the module. Other than that, all looks fine.
