stafford Need to know the pin outs on the ECU, I have a pdf of the manual but can't read the image when zoomed in. Help!
stafford Right ECU, wrong pins somehow. It appears the ST4S 2001 doesn't have a wire off pin 28. Looked at two looms and they are both missing the pin/wire.
griff851 Are you sure your looking at the pins the right way. Because if you look at the opposite side it's B19 and A20. B19 is empty and A20 is some sort of analog earth. Which would make more sense.
stafford The early ST4S loom appears to be missing 1 and 28 starter and kill switch from the grey plug, in reverse the two components go to 17 and 27 on the grey. This of course goes against everything I can see about 59M ECUs on the web. Early ST4S diagram anyone? or.......late ST4S loom or S4RS or S4R anyone?
stafford Dear all, turns out we are all good now, well I hope so. It does appear that the early ST4S loom does NOT conform to he standard for the 59M Magnetti ECU pin out though. Any info I could find appears to show the later pin outs and coupled with a duff ECU we were chasing ghosts. So had the spare ECU re-flashed to remove the immobiliser and we now are in a position to go forward. Thanks all and Griff
