Where does the Taillamp wiring harness in an 89 trans am plug up? Do I have to pull the rear seat?

AFAIK it's entirely inside the car.

The "Fischer body" connector is just about right under the clutch pedal. AFAIK there's only one other connector from there all the way back to the lights themselves, which if memory serves is either in the fender well behind the "glove box" or near the hatch latch.

What are you REALLY trying to ask?

I have a short somewhere and I need to unplug the taillamp wiring harness to see if that's it or rule it out as the cause of blowing the fuse.

Start at the "Fischer Body" connector then. It's just under the edge of the carpet, relatively eeeezy to get to.

I dont see a main connector here under the kick panel. It goes straight to the fuse block.

I pulled this loome apart and no connector, i apparently dont see it.

That's not the kick panel, it's the rocker panel. The kick panel is next to your shins when you're in the seat; in front of the door, down low, below the dash.

However, I am misshapen: the connector in question is on the left kick panel, near the hood release. Sorry, was thinking about a different car. 12-pos connector all in one line.

It's a connector at the back of the car on the driver's side. Open the locking storage compartment and feel around behind the cardboard 'box'. Technically it's clipped into an anchor snapped into the body, at the moment I can't remember if it's clipped near the top or the back, either way it's around there somewhere.

Is the one you are talking about? I unplugged it, turn signals and brake lights work with it unplugged. Still popping fuse.

That's the power door lock relay. Back up to my last reply. Look where I said to look.

Which one is it?

Drew, there isn't a connector here. I think. On the 91 and 92 they are.

86 Firebirds have the disconnect in back too. Can't imagine why GM would move the harness to the front between 86 and 91 only to move it back. Follow that harness forward and you should find a disconnect.

The bundle in most of your pics is the power accessory harness for the locks, windows, that ****. The harness that goes to the fuel pump and the tail lights is the bundle that runs down against the firewall and toeboard.

GM quit connecting the "body" harness behind the driver side Kick Panel in 87 I think. Starting in 88 the wiring changed and the "body" harness was incorporated into the Dash harness. The plug your looking for is behind the rear seat "arm rest" plastic panel; this pic is an 88.....

John, that's where I was thinking it might be! Thank you!

tail lamp harness was good! Found the guilty culprit, a beautifully blown back up bulb!
