As the title says im looking for the correct ecu ground location, when installing my lc-1 the other night with a fellow member who has a 94 my ecu ground was not to be found in the same place.

I googled it, used the search function, as well as m.net, so if someone can snap a picture of it that would be sweet. Thanks

Elesjuan probably shot you a pic of the 1.8 because your post made it sound like you had a 94. I reread it and now I see that your friend had the 94. Your 1.6 ground is on the back of the head.

Oh you didn't specify 1.6 liter.. I don't know anything about those.

FWIW I used all of the factory wiring for the LC-1. Pulled the connector off an old o2 sensor and crimped some new pins on! Viola! Plug and play!

Of course, I also overdid a lot of grounds on the car.. Ground problems can cause nightmare gremlins that are really hard to find. Be proactive, prevent them!

On the hot side? Does it happen to go from the head to the body?

1.6L ground points are labeled in this diagram:

2 on the above diagram (Black/light green) is the ECU signal grounds on 90-93 AFAIK. I soldered the system ground (white) of the LC-1 to a ring tab and bolted it to 2. The heater ground (blue) of the LC-1 I soldered to a separate ring tab and bolted it to the ground under the clutch master. This is the high-power ground (injector and other outputs AFAIK), all black wires. Absolutely no LC1 issues for me.
