Can anyone tell me if I have to run a relay when adding lights to one of the five auxiliary switches thet came stock in my ram 2500 4th gen?...It looks like a direct plug in under the hood with its own fuse box...I was thinking direct plug into one of the 5 slots and the run a ground....however someone told me you have to run a relay....I thought it contained its own relay and I don't want to be redundant ....
thanks guys appreciate the help
