Yes and No
RClark - Any good tire shop or parts house should have the tire valve assemblies you are looking for.
No - The DRL unit will not go on a non DRL truck. I found out the hard way, just knew there was a plug on the truck for it, ordered the module and its still sitting on the shelf new in the box. I'll make someone a good deal on it. I ended up using 2 relays and a blocking diode to make it work. If you have sport headlights, one relay will work.
