Do you mean taking a dual headlight housing and turning into a quad?
no its easy. just take out your factory st lights, unplug your head light and plug it back into your new head light assembly. on our st trucks the headlight harness plugs right into the head light bulb, but on the quad headlights there is a little harness that has a connector hanging out the back of the head light assembly. just take your factory plug and plug it into the new heads light assembly. i hope i didn't try to over simply-fly it.I apologize about not being more specific. I ment taking a truck that came with dual headlights from the factory (like a ST base model), then swapping them for quad headlights (like a laramie).
So a quad harness is just plug n' play once you remove the dual harness? All you would need to do is get the computer re-programmed? Sounds simple enough.
I appreciate the help fellas.
well that sucks did they tell you why? my dealer told me they could. but i am waiting do to mine so i can have the code add for key fobs at the same time. thanks mopar71I have done this. Everything is plug and play but the hi's and lows won't stay on together unless you get your truck flashed by the dealer. Sales code LMES is needed from my research. I just went fri to have this code added and they told me they could not so I'm SOL. I put better bulbs in so it doesn't really bother me.
