Engine loom firewall plugs
I have the genuine ford sierra '90 wiring diagrams but have been unable to locate the 3 firewall plugs that connect the engine loom to the main loom. I am sure they are in there somewhere and I must be blind. I would expect them to show up in diagram 5F which is the engine management - fuel injection for the cosworth as this shows the ECU connector and all engine sensors but it does not seem to show the firewall plugs. Antone else with these drawings come across them or have a diagram of which sensors go through which plugs. Also does someone know which sensors use shielded wiring and weather the shield is supposed to be connected via a pin on one of these plugs (as opposed to just the inner wires being sent through the plugs) Thanks David
