I bought a relay about a year ago and have tried to install it many times. Today I think I am on the verge of the install. This relay is a dual head light relay. It has two terminals for the head lights which might mean I can run my fog lights thought it as well( Please chim in here if I am wrong) It has two fuses inside as well. It says it's Heavy duty on the case . I took a couple of picks for everyone to look at.
