Anybody know if I need to connect the green EWS wire from X20 pin 7? I'm in the middle of re-pinning my old X20 engine ('97 S52) side into a C101 engine side. I have an OBD2 reflash with EWS delete, secondary air pump, rear O2 and vac cannister deleted, etc. It's for a strictly track car ('early '87 325IS).
I would assume it is not needed, since I did the EWS delete, but I don't know if the wire normally carries a voltage signal needed for starting/running, and the EWS just disables that, or if that wire carries some sort of "disable" signal to prevent starting, and the EWS cuts that? Or if the wire does nothing, since EWS disabled? See what I'm saying? I have been through the ETMs, and I just can't tell what the real function is, with EWS deleted. I've also searched here and elsewhere, to no avail.
Anybody dealt with this already?
Thanks for any shared wisdom!
