Is STILL Here?
Another vote here for tapping off the fuel pump relay. Only reason is in case you have to do diagnostics or anything that's in extended key-on/engine-off situations. I don't know how tough the AFS74 is, but some sensors can be thermally shocked if left in one of those super hot conditions without exhaust flow. They can handle the heat, but a few spittles of raw fuel or water vapor immediately/shortly after initial startup can zap a sensor (at least the heater part).
