So the ones I bought off Amazon were already plug and play with the original 6054 bulb harness. It also has a lead wire come off of it that you can wire to whatever signal you want for the outer daytime running lights, or you can do like I did, just tape the terminal ends and not wire them up, and they come on when you have your lights off, in essence becoming DRLs basically when your headlights are off (of course they're also on when your headlights are turned on, also). So far I LOVE them and have zero issues with them from the start. Great fitment, plug and play, and perfect light throw/beam with a decent cutoff. Here's the link to them:

Love 'em.
And yeah I was in the same boat. I bought my old girl as-is, not running and took a total leap of faith on it, but seeing the overall condition I figured it had to be decent. Thankfully the odds were in my favor; needed nothing more than a new coil, alternator, and a belt to get her going. Being at just over a 100k, I figured why take a chance, and just use this as my major interval to get EVERYTHING done, so I did ALL fluids, flushed if necessary, all filters, all serviceable maintenance parts, and a new front end since the parts are available to me cheap (parts manager for a major dealership), and then handling the rest as it comes about. Needless to say my goal is to properly restore this jeep to 100% over the winter before I move into modifications. My goal is to hopefully build this jeep the "right" way this time, any getting it cheap helps to put the money into the "right" parts. Still trying to keep this jeep on a cheap budget all in however.
