My sierra handbrake switch does not seem to have any wires coming out of it nor does it look like it ever has........

how the hell do they work?

There should be a tab on the drivers side to which you take the feed with a female spade connector on it

Normally you'ld have one wire coming out of it- there's a spade terminal coming out of the back of it. The switch acts as a switch to earth through the handbrake body...

Mine was missing a wire too. But with a bit of cunning triming of a spade connector it can be slid in where yours is missing below the spring if that makes any sence ?

Mine had no wires when I ripped it out of a car at the scrappy.

Like so. Posted on the right thread this time.

If that spade is missing as said you can make a spade terminal fit in there. All that happens to make it work is a contact on the pin and when it goes up and down it contacted the spade and gives you your connection so its easy to make something.


I have a spare of one similar. u2u me your address and ill stick it in the post if its any use,
