Any body know part number or where I can get fog light harness for my gen 2 Prius I order factory fog light I’m not sure if there is a harness already there or I have to buy harness?
Hmm ... 2010 has a separate, inexpensive harness that just goes with the bumper and the turn signals and fogs if present, and just connects to the main engine bay harness at a plug ahead of the left wheel. But it looks like Gen 2 doesn't have that, and the fog light connectors just belong to the main engine bay wire harness. If that was made in fog and no-fog versions, replacing it would be a pretty impractical expense.
I just ordered a pair of these from Amazon yesterday to replace the ones Maaco painted, which come with a wiring harness and switch (for non-OEM imstalls). The only set with glass lenses I found that includes the grill pieces and harness/switch. https://www.amazon.com/gp/product/B01MYAC7WK/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 uh-oh…Maaco!
