I have a 93 civic si and no matter what i do i cant get the cel to come on. When i turn the ignition on the cel doesnt come on at all. Ive replaced bulbs, swapped clusters, and nothing has worked. I'm also missing an 02 sensor so i KNOW it should be throwing a code. Its a stock gsr and it wont run on a stock ecu so i know something is wrong with it and i would love to check the codes. Car is tuned on uberdata. HELP

Some one may have cut the CEL wire in the cluster connector or ECU connector.

Any idea which wire this would be?

Grn/Orn wire

Check your ecu, it may be fried, or not the right kind. When I swapped my B18b I used the stuck ecu for a week until I found the right one, I didn't have the 02 sensor hooked up and I didn't have a cel.

I'm pretty sure it would still come on when your turned to accessory when the main relay clicks
