Ok, again, thanks for all the help. I went down and looked in my car, and i found the compass and it is already wired in. I think i found the temp sensor in my bumper and it's already hooked up. Just to clarify, how would i remove the black plastic grille on the front of my car, just to be positive? Also, i have the passenger airbag sensor in my trim plate. Would that make it any harder or not?
