I can give it a whirl. Sorry if I'm being dense and/or stubborn - I guess I'm a little hesitant to start pulling wires just yet without understanding quite what I'm doing.
Which wire, then, are you suggesting I pull from the ECM? Based on the diagram you linked in post 7, it seems to me that the Yellow/Black Wires are actually powering the ECM itself downstream of the PGM-FI 1 Relay. I downloaded an ECM/PCM pinout, but for the life of me cannot find the link. I found the two yellow/black wires at the ECM - so I'm willing to try yanking them.
I anticipate I'll get the same issues as this guy, "P0685, which is "ECM/PCM Power Relay Control Circuit/Open.""
