i think its a t20.
there are 2 screws; you crawl under and they go into the back of the light .
thenm once you have them all the way out. get a good light in there.......there are 2 like PINS that are part of the light that come thru the back of the bumper and click into plavce. you have to squeeze them in to release. be careful sometimes when you push those the fog light goes almost shooting out the front so be ready with the other hand or a helper or a big towel to catch it.
the wire is just a 2 pin. pretty simple release.
