5 pin bosch style relay

Actually Peter, they aren't, some of the drawings have the terminals reversed for convenience of circuit layout, whereas when I do my little drawings and try to keep to the 85NEG, 86POS convention, they end up looking like maps of London's Underground! As Messrs. Idiot and KP will confirm ISO convention makes 85 NEG and 86 POS. That's how the car manufacturers wire them and as you know VERY relevant if inbuilt diodes or pre-dioded in the wiring looms as some car manufacturers loom them.
