hi all. I currently doing a 1.2 16v swop and I read on here for the diagrams for the swop but when I come to do the swop Ive been stopped in my tracks we the wiring for the d4 plug for the sei loom to punto 16v plug as only got 3 wires to match up. black plug is he punto 16v and the gray one is the sei loom

if you used google or looked in the “guides” section of the forum you’d have found yourself a handy article with everything to do with the wiring.....
