I have 2 Roland JX-10 synthesizers from the 80s. I have made on good of the two and then fixed the other boards. I am left with a JX-10 with a missing, obsolete wire harness. I asked the best synth technician I know, " What would you do?" He said " I'd hardwire it". There are about 8 PCBs. It would be very difficult to solder from the back and reinstall. He suggested soldering from the top. I trust his opinion but he did not have time to explain or give me any tips. Following Shrouded pin receptacle removal, I will have about 200 wires to solder in groups of 4, 6, 10 and 12. Holes are 2.4mm apart. Traces and solder pads will be facing away from me. I am in need of suggestions, advice and tips prior to attempting this project.
Thanks

In other words, the heat from the soldering iron can only get to the board copper through the wire being soldered into that hole? If so, that doesn't sound like a very good plan.

I have OLD molex connectors. I can't find mates.
4 pin, 6 pin, 10 pin and 12 pin
2.4 mm pin spacing
Some are as long as 60 cm
About 20 connections in total. What is the best and most economical way to do this?

60cm? That borders on the absurd. How about a photo of what you're dealing with. I'm not sure, so just imagining a motherboard power-entry kind of connector. But that isn't shrouded pins. Or... a berg connector, which is more like a disk drive connector or board-to-board connector.

Power supply is on the far right and it has 6 PCBs as well as key sensor connectors.
I decided last night instead of going crazy with wires and solder to use my head a little. After about 4 hours looking for the said "Obsolete" Connectors, I found them. Not obsolete at all! Molex 050375xx3. X being position count. I have about 40 connectors coming as well as 350 crimp contacts. There are 261 contacts in total. I ordered the extra 89 because I have never crimped this type of connector and will probably ruin a few. I don't have a crimper and am hoping I can solder them.
