Re: Checking CELS and the light is on solid?

IIRC, in 1992 the california cars had a different EGR setup to the other USDM cars. There's a wire on the ECU harness that you ground to tell the ECU to use "california mode" instead of "49-states mode".

But after 93 they fitted all USDM cars with the california setup. I think you can still switch the later cars into "49-states mode" by disconnecting the california wire.
