My 91 GSX... It doesn't have a Fuel Pump Test terminal. The FSM says it's right here, in the firewall harness, behind the battery. Supposed to be a Black wire with White stripe. I've owned the car for 22 years and never found one. Anybody else have the same issue? I'll fab one if it isn't shown to be elsewhere.

Is your car a '91? See the note here, if so: The 1990 Engine Control Wiring Harness

Edit: silly question... I didn't read your post's first three words!

The links go to missing images. But he's saying SOME 91's didn't have that terminal?? Any details on that? He mentions a TSB. Anybody got that?

His links are basically going to show you what you already know - what the connector looks like and where it's supposed to be located. @steve - would you happen to have the TSB number for the missing fuel pump check terminal connector?

I don't have any DSM stuff up here with me in the mountains.

I may have the TSB itself back in Illinois assuming I can figure out which computer it was on.

There were some number 1991 cars that were missing the fuel pump check connectors in the harness. There wasn't a recommended fix just the notice.

Let's assume fir a minute you have the connector. If I recall it isn't just sitting there. Its taped very well to the harness and difficult to see. To even use it you almost have to untape it. I always left mine free once I did that. You probably already looked hard enough but thought I would throw this out there.
