Default Marelli wiring harness... where does it go?

I have almost everything unplugged on my injector harness except one last part... in this photo, the wire by the screwdriver blade... where does that go? There is a wire going down to the transmission, but I think that's the plastic wrapped wire between the screwdriver and the orange flashlight.

In the foreground is the oil pressure switch. This is a wire that heads down behind the engine... to places unknown.

It is attached to the left side of the tranny. Iirc reverse light switch.

More likely kickdown perhaps, or the flywheel sensor? I know nothing about Marelli cars, but the reverse light switch is on the gear selector on Lucas ones.

Both my marelli sensor leads are in that flexi conduit shown in the pic so flywheel sensor would be my guess for that one. The kickdown wire from memory was in a simple black casing like that near the screwdriver blade.

Reverse light switch is on the selector on my 89 as well.

There is a wire from the kickdown switch on the throttle cable near the capstan that goes to the left side of the transmission. That looks like the one.

The plastic cable sheath between the screwdriver and torch is the engine speed sensor (flywheel) wire.

It is the kickdown...

Marelli senors use quite thick wires...

Hmm no dice on the kick down. That wiring is part of the console harness (I dug around). The flywheel sensor is in that corrugated plastic tube. I'm tempted to just cut the thing off and install a blade connector. Even when I find where it goes it will be hard to install again.

Nvm! You all meant the kick down on the transmission not the gas pedal. That's it . Looks like the harness will come out in one piece.

And dammit it's screwed to the side of the transmission. No way I'm taking off half the exhaust to pull a little wire. Snip-Snip + Blade connector it is!

Only one little screw. You can get to it without removing the exhaust...
