It's not a pin it's a tiny female spade connector as found in mini ISO blocks such as the type behind my Alana head unit. This shows the type of connector in more detail. http://i108.photobucket.com/albums/n25/joonspoon_2006/SCN/MINIISOYP1.jpg The problem is that the wires are not the exact ones needed to do the job and the interior light wiring is on the right hand side of the car. The wires can be used no problem. It's easier to use a scotch lock to splice into a power feed. It just isn't necessarily the power supply the factory would use. I'm trying to keep the cost down. At the moment this job should be about £15.00 fitted. I asked SEAT tech dept for the correct part numbers (they must exist) when I asked for advice about the power feed but I'd expect the power supply wire to be fairly long as I reckon it needs to go to the roof or the other side of the car. I'll let you know. Guy.
