Right, I hope I am on the correct thing here. If you look at the picture of the connector with 4 terminals the 2 connections to the left had brown wires attached and the 2 to the right had light blue wires. If you number those terminal 1, 2, 3 and 4 then I could get no reading between terminals 1 and 2 and no reading between terminals 3 and 4 but when I tried terminals 1 and 3 I got a reading of 5.3 ohms and a reading of 14 ohms between terminal 2 and 4 which is not what I expected. I thought it would be adjacent pairs that should have a resistance or am I completely wrong?
