Ye olde wiring harness? When to replace?

Not to mention that those butt splices likely were improperly installed and they're UGLY. I'd say that the easiest fix is a new replacement harness from Year One. Their Mopar stuff is made by M&H in Cali and in my humble opinion, just can't be beat. It's not the cheap way, but they have all the proper plugs and connectors and the wire lengths are correct. That saves a LOT of aggravation!

I learned in the construction industry that there are three desirable outcomes in any job. You want cheap, quick, & good. But you can only have two of those! If it's cheap and quick, it WON'T be good. If it's good and quick, it WON'T be cheap - etc, etc....
