Various links I have collected in troubleshooting & repairing ECU and various sensors & wiring to all my buddies at these 3 newsgroups who have helped me out a LOT and other folks looking for info on Eclipse projects....
I'm still looking for a 1G (1990) ECU schematic if some can post a link or (for shy fellers) send me an email at snipped-for-privacy@yahooHAT.com (pls remove YOUR HAT first!). If you're sending an email, pls let me know by posting here first.
Note to alt.home.repair folks -- if you're not into fixing cars, pls just ignore this. I know that group is mostly for work around the house, but I have heard more from folks there than at all the auto groups combined.

The wire color layout diagrams accompanying each picture are as seen FROM the HARNESS SIDE of the connector with the release tab (for a male side connector) or locking notch (for a female side connector) on top. They should be color coded correctly, but if there is a disagreement with the letters and the color of the letters, go by the letters. When two colors are listed together, the first is the main color and the second is the color of the stripe or tracer. The letters represent the following colors:
B - Black W - White R - Red G - Green L - Blue Y - Yellow O - Orange Lg - Light Green
