I didn't do the soldering on it, though I would have liked to as an escape from my former boss (that's another story), but I did watch the technicians doing it and from what I remember:

• First, double check your wiring diagram at both ends. Had a right fun time explaining to my boss the reason for the days of delay was whomever did the connector on the motor/gen socket had wired it up backwards because they hadn't flipped the wiring diagram. And disassembling that was a bitch.

• Triple check the orientation you're working from and it's always better to borrow a second pair of eyes than redoing it.

• Make a spreadsheet with the connections and print it out large on A3 paper (or US equivalent size).

• Read the connector documentation a few times and have a go at disassembly then reassembly without the pins.

• Cut your wires to the required length and bundle them together into a harness using kapton or electrical tape.

• Make sure any glands that need to go over the end of the connector are slid over your wiring bundle

• Work from the centre out, it makes pin insertion much easier.

• Double check before inserting a pin until it clicks, they're more difficult to remove than insert.

• Check both ends using continuity on your multimeter after each insertion (if that's possible) and mark off the connection on your A3 sheet using a highlighter.

• Run a continuity check after you've inserted the last pin.

• Finally, slide the gland fittings and thread into place.

Please verify this advice yourself as it's been more than 4 years since I've worked with these connectors and you should never blindly trust strangers on the internet, let alone those giving advice.

Happy wiring 😊
