can you give me the name of the kit you are talking about? part number would be helpful too. production date of your vehicle and did your truck have daytime running lights or not? you have two fuses, one for each headlight in the engine fuse box in the early style light system. it has a relay from the gem module. the late system runs the relay through the security
module. you will have to check powers and grounds to see what you're missing and where you lost it.
