What one is the sending wire on the 02's so I can hook it up to the gauge?
Thanks

You're going to have to get a schematic from Ford. That's what I did. I think it's green with purple, but I don't really remember. Once you get the schematic and find the wire, use a voltage meter to check the volts. Just poke it right through the wire and take the reading. The voltage should constantly be moving. Sorry, I've looked all over the house for the schematic but I can't find it. Good Luck!

Take care

I also installed a toggle so I can read the LH and RH independently, works good. I also choose to hook the wores up at the EEC instead of under the car at the O2's.

Installation instructions for a left and right DPST switch. (Radio Shack)
Red = 12v Ign. (5 amp inline fuse)
Blk = Engine grd.
Violet = Center pole of switch to the
Left switch pole = right hand oxygen sensor / number 65 (gray/blue) at EEC
Right switch pole = left hand oxygen sensor / number 66 (red/blue) at EEC

Soldier connections of jump wire at switch pole and shaved wire at EEC.

The violet wire is coming out of the back of the A/F gauge and is connected
only to the center pole of the DPST switch.
Don't cut the OEM wires to the EEC, just shave back the plastic insulation
that covers the wire and twist the wire around the exposed bare OEM wire
(65&66). You should use a pencil type soldiering iron a soldier all the
connections.
