[QUOTE="Jiffy, post: 15636307, member: 124414"] So - what's an EEC? Same thing as the ECU with a different name? Are you certain the FPDM pulses the GROUND wire to the pumps? That's not what I thought/expected - here's the wiring diagram that I was given to use, and I think it shows the BAP on the power wire in series with the inertia switch, and I think that has the power from the battery? Or do I have it wrong? the diagram clearly shows the ground wire as being over in the rhs bottom corner, and there is a '+' and '-' wire going to the pumps. It's my understanding that the wire from the inertia switch is the high-current 12v from the battery and the FPDM allows more voltage through when commanded by the ECU. Or do I have it completely bass ackwards? [IMG]http://www.mustangphotos.com/photopost/data/500/medium/Final_BAP-FPDM_wiring.PNG[/IMG] [/QUOTE]
