Parking(Emergency) Brake Light
Hi all,
I was wondering If any body could tell me where the switch is located for the parking brake light. I was fooling around with mine the other day. It has never worked and I would like to change that. I took it out and looked at the wires. My test light showed it had a constant hot wire and the other I have to assume is a ground. I saw no switch to complet the connection. I reied to follow the wires but they go up the dash into a big cluster of wires that are all taped together. I am sure someone has had this problem before. I just figured I would give it a try to try to save me some head scratching.
Thanks to all who try to help,
David

wow. I would have never guessed that it was a pressure warning light. Thanks for the help. I remember about 7-8 years ago my m/c went out when I was breaking on the freeway no less. I don't remember that light comming on but I sure remember the loos of pressure I thought I was going to plow me a field of cars. Well anyway thanks for the help.

The last time we discussed this, we came to the conclusion that some of the '71 and '72 trucks had this light activated by the e-brake as well as the differential valve. It might have been a dealer add-on at that time. It is also normal for the light to come when the key is in the "start" position.

Based on what I've seen, it's not really a pressure light as much as it is a difference in pressure light. You can find the switch for the light in the middle of the differential valve. It should be on the left frame rail just about under the driver's foot. Low pressure on one side or the other results in a plunger in the switch dropping and turning on the light.
I did some research on it because mine won't go out even though I tried the correction in the shop manual. I may have a bad switch, but they're hard to find.
