Customer has booked me to replace I/lock wiring. He describes a Double Wire in Plastic Thingy ! A single Thick wire in Plastic Thingy, and a thin Green wire. I’m ‘Pretty’ sure which is which, but he lives about 28 miles from me so just lookin for Back-up confirmation. I,ve got Spare I/lock here, and terminals used are 1, 2 and 3. Cheers Chaps 🙂 and Chapesses 🙂
