@CodingItWrong@oldbytes.space Here is the link to the wiring harness I found on eBay: https://ebay.us/m/zZFyNy This seller advertises a trade-in rebate for old, dead MDD power supplies. It looks like he offers a rebuild service for these power supplies, and he sells rebuilt units, though both of these options are well beyond what I’m willing to spend right now on this project. I’ll be contacting him to trade in mine once the harness arrives. I hope this is helpful.
