Checked the schematics and can find nothing. White wires marked 70, 72, 74 located by the ECM. Click to view attachment

FI computer ground wires IIRC. Thay all go to a multiple spade lug connector.

Maybe not after looking at your pic again.

I just wish to hell you could still get your engine steam cleaned. It's been about 17 years since this baby got a bath.

Many L-jet cars had this wiring which is for an altitude compensator that was rarely installed. Put a little tape or shrink wrap on the ends so the wires don't touch each other.

^^^ yup.

Thanks guys, much appreciated!
