My m416 has brand new 4-pin wiring, but I'd like to swap in M-series lights (with LED). How do I wire them up using the standard 4-wire trailer wiring since they have the military outputs? I don't have the original military wiring harness/plugs, so that's not an option. Thanks in advance.

I hope this helps. Your lights should have male connectors with rubber boots to seal.....I crimped on female ends and plugged together. I left the rubber boots on, I should be able to find the counter parts to make them seal up real good.
