7 pin cable
Due to a bit of age/corrosion, I have decided to replace the 7 pin plug/cable on the trailer. As I usually do when I am about to tackle something I haven't previously dealt with, I searched the net...

If I may inject a tip here regarding smaller insulated wire terminals.
When choosing the type of wire terminals to buy, you might want to specify NYLON insulation over PLASTIC
Wire size terminals are color coded
Red for 18 gauge
Blue for 16-14 gauge
Yellow For 12-10 gauge
Nylon insulation is tinted like red, blue, and yellow but unlike plastic you can see the barrel of the terminal. It is translucent. Plastic is opaque.
Why Nylon? Nylon insulation is a lot tougher than plastic. This allows me to choose a different much tighter crimp without puncturing the insulation.
Most crimpers give a () shaped crimp. Keep searching on Amazon or eBay and you'll stumble upon a () plier that has a < on one side. The tip makes all the difference.
I've won bets from people who claim the tip shape of the crimp will hurt the nylon. It can't. But it squeezes the terminal much tighter onto the wire.
I have not tried this with terminals that have heat shrink ready to go, so I urge caution. In fact with heat shrink terminals or solder shrink terminals I would urge checking into a vice grip type of crimping pliers.
