Quoted from radium:
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
Its not as hard as you think. The first time I knew I had to replace connectors I was really nervous about it, remember these two key things:
1. You cant really mess it up, if you crimp a connector and it comes out mashed and no good, you just snip it off and try again. That's why you order a ton of them like tracelifter said, they are cheap and good to have on hand anyway.
2. if you stick it in the connector and its no good after you test it, you just use a tiny screwdriver to push it out and try again.
You can try as many times as you need to, you really cant screw it up too badly as long as you don't mix the wires up. Take pictures, make notes, do one at a time rather then clip them all at once before recrimping them all.
The pic above illustrating the proper crimp is intimidating but the key things to take away are you want the first collar on the end to go around the insulation, the second collar goes around the bare wire, look at it after you crimped did they curl down and grab them good. Lastly, your goal is to only have the bare wire in that second crimp and maybe a little past, you don't want a whole bunch of wire going past that second collar. It gets easier with practice and you will become a champ in no time.
