I have an 85 GL wagon and in the engine bay near the windshield, there are no white single-pole connectors... so what do I have to connect to read codes? Thanks.

The plugs are under the steering column next to the ECU. Need to connect the green plugs to read them.

ECU Codes

So both green together? And it wasnt quite clear how to clear them?

Thanks.

So both green together? And how do i know what mode to be in, as in "test" or whatever other ones there were. And it wasnt quite clear how to clear them?

Thanks.

The green connectors together for test mode. Then find the black connectors, this is the dealer check mode. Once you check these, connect both together, I think this will clear the codes. If it doesnt, just disconnect the battery overnight.

Ok so now my ECS light comes on when i drive, and wont go away, I checked the codes by connecting the 2 green connectors but it doesnt show any code, all it shows is a 7 and a 3, which means its a 4x4 Cali car... I'll try to clear it tomorrow. Very weird. Now maybe I know why it didnt have a bulb for the ECS slot. Thanks.

I checked and I only have green connectors under the dash, no black or brown. Where are they supposed to be at? Thanks.
