Default MK4 Escort EFI ECC IV system.
Hi Guys,

Does anyone have a picture of efi engine management system wiring diagram? For some reason the Haynes doesn't show the EfI system.

I have a cooked ECT coolant temp sensor, but the feed in at plug is 12v were I'm thinking it should be 5v, it was rebuilt by someone, so I wonder what has possibly been wired in.
