DIY Tester Cable for Pin Connectors

[liquiddog]

I built this this morning and it will make life easier. The connectors are Deans Ultra Plugs and are low resistance. Useful for resistance testing.

I harvested the pins off a climate control valve exchanger but these pins are all over the car so any off junk parts will do. I thought they'd need to be desoldered off the copper but it turns out they are just press fit. I ended up just pulling the copper off.

See attached pics. I already had a deans plug attached to banana plugs for other DIY attachments. Only gotcha with these connectors is to plug it into another connector while soldering, or the connector housing gets hot and the pins move. I'm using 12 awg wire so it gets really hot. It won't fit right afterwards. I've found vice grips work well to hold the connector in place, while "helping hands" hold the wire.
