    I'm replacing some flaky IDC connectors on my HH displays with Molex/trifurcon. Some of the IDC connectors are wired in series, so that the wires do not terminate at the display but instead continue on to another display. Is there a proper way to replace these?

    I'm guessing I cut the wire where the IDC bites it, strip two ends, and crimp them both into one pin... but I know there's a lot of rules about properly terminating connections. Wanted to make sure this is OK before I cut these wires.

    (NOTE: I'm not talking about a pin that loops to another pin in the same connector, I mean two connectors in series on the same wiring)

    Thanks everyone. The connectors I'm rebuilding are 19-pin so it's gonna take me a while to pigtail those things, but it seems the proper way. I think there's enough slack wire that I can make it all the same color to the pin. If I do that and keep the lengths correct it should look pretty clean.

    Thanks for that link Fanatic. I had the same concerns after reading the pinrepair connector guide. I had no idea there was so much to proper crimping.

    Quoted from TheFamilyArcade:

    Any good wiring tutorial vids around?

    What are you looking to do exactly?

    Quoted from tracelifter:

    Order extra pins and practice your crimps before you do the actual repair.
    Look at them and pull on them to make sure they are tight and not bowed.
    You will also want to replace the male pins on the board at the same time.

    Will do, thanks!

    No male pins, these are for edge connectors in a Sys80. Should I reflow those? Or only if I still have problems?
