US 1984 928S

What is the electrical component/box that is attached to the right side of the passenger under-dash tray?

Does it have the label Jetronic on it?

[hbueno]

It's a black box, maybe 2"x2" x1", that is attached to the shelf itself with wires that run forward into the footwell. It's not the L-Jet box which is mounted to the side of the footwell.

Might want to take a picture of it but chances are it is the bulb control unit.

If its Porsche, it will have a part number on it.

Do you have an after market alarm? It could be the "shock" sensor

DOH Sean answered this sorry......
that box is the controller for the bulb control monitor,
if its not connected you will lose the brake lights

I should have taken a picture when I had everything apart to install the Lizard short shifter. I didn't think of asking at that time.

There is an Ungo alarm system that was installed back in the 90's. I don't use it and the only thing it seems to have broken is the ability to lock the doors from outside.

Next time I remove the tray, I'll take a picture and post it.

Does it have a small horizontal 3 position switch with a red LED indicator? I have the same type of box if that's what you're talking about.

Hugo post 4 and 7 answer your question.

Of course posting a picture will give better results

Here is the box in my car

It looks like my frankenstein car had a kill switch (likely disconnected) also installed. I'm afraid what I'm going to find lurking inder the dash and footwell.
My next project is clearing out the garage.

[Pete R]

That switch could also be to switch modes on the alarm. (valet)

Over time aftermarket alarm systems top my PITA list for the 928.

Mine appears inop with no power going to it.
