Ah, you already knew about the 2 lugs

Im sure Rod might have some info on the multicoil bit of it too, Ive only used it on coilpack so not positive on exactly how the indifvidual coils go without looking at the manual, but you're certainly in the right ballpark with the rest

At least you worked out the 1342 thing on the injectors, loads of people think the 1234 on the ecu refers to cylinder order not firing order!
