Hello everyone I’m new to the forum and I am trying to wire up a new 12s 7 pin plug that’s on my Ifor Williams trailer Tipping trailer. The original plug was damaged and when I open up the plug only 1 of the 4 wires were connected to it, the other 3 were loose. I traced the wires back on to the tipping trailer leisure battery and 2 of the wires were connected to the positive terminal and the other 2 were connected to the negative battery terminal. Could someone tell me how I wire the 4 wires to the 12s 7 pin UK plug? Thanks in advance for your help..
