Plug and play - Headlight Relay Kits

Are all single headlight Mopar relay kits created equal? I bought one from you when I was picking up my engine from Brian. It was for my Plymouth single headlight car, however, my single headlight D100 is really close to getting on the road.
Can I use that kit on the truck?

The truck will have different lengths for the wire runs. Same basic approach to the kit.
