Message	DO NOT ATTEMPT THIS FOR CRYING OUT LOUD Okay, I'm guessing that all us 90-94 owners are thinking "Gee, on the surface this seems like a pretty easy fix!" 1. Pull the fusible link for wire #58 at battery 2. Cut wire #58 near the ecu and splice to wire #45 near ecu. 3. Run an unswitched FUSED (please!) power line (battery/radio memory/etc) to pin 58 on ecu. The possible problems *I* see are: The Relays : Ignition, ECCS relay, Fuel Pump. Do they require constant power? -- me The wiring diagram may be more logical layout then physical: Could this cause us issues? What? - You Your thoughful question here - You So, start ripping me a new one, and maybe we'll get some answers along the way :)
