Well let me first say how grateful I am for the informative responses. I have a few options to work with now. I drove up to Flagstaff yesterday and found an 87 GL. It has the Revolution Sensor. The part number ends in 080 instead of 000. So, I'm not certain that it is the same. Everything else on the outside looks identical. My GL doesn't have the relays and this one did. So, I got the relays as well. I've got schematics for both cars and will track down if the wiring and function seem to be the same for both years. If that doesn't work, I can wire in the relay as described in your posts. So thank you very much for all of the assistance. I'll let you know how this works.

I have an 1986 GL wagon, base, 1.8L. The Subaru Part # 22631AA000 Revolution sensor is bad. This part is not available through any Subaru distribution. I am trying area junk yards with out success so far. I know that I can by-pass it by jumping power to the fuel pump and ignition coil. This does not seem like a satisfactory solution, not sure. It appears that many Subaru mechanics have never heard of this part. Some of the GL's of the same year have relays instead. Fuel injected and turbo vehicles do not have this sensor. Does anyone first know where to locate one? If not, can someone give me a layman's explanation on how to substitute something else? Or, does anyone know where or how one can be re-built? This is a 2"X2.5"X 1.25" box with six blades in the plug in from the wiring harness. It is manufactured by Mitsubishi. It senses revolutions to switch power on to the fuel pump and ignition coil. Black in color, likely not the blue one. Mine is mounted at the base of the steering column, right side, under the cover panel. Another post on a different thread described it as by the hood latch on the driver's left side. I have found those to be the blue housing unit by Denso with 5 pins. It will not work.
