I looking for a headlight wiring harness for 1985 D-100 with a 225. Part # 04362102. Any help on finding one, it was my Dad's truck and it going to my son. Thanks, Steve.

The factory headlamp harnesses on those trucks was severely underspecified—marginally adequate at best, when new. They aged poorly. You will almost certainly not find a new one, and a used one will have four decades' degradation. You can do a whole lot better without spending a pile of money; read this and send me an email from that page, if you like.

Too many people who were born on third base actually believe they've hit a triple.

Thanks for the info I will check into it.
