You know the saying "One thing leads to another"? This all originated with me fixing my parking brakes by replacing all the cables. https://classicbroncos.com/forums/threads/how-do-i-stop-the-parking-brake-from-doing-this.328392/
Then for some reason I couldn't stop working on Bronco stuff. Years ago I had to cut off the pedal to clear my home built roll bar. So to apply the P brake I had to step carefully on the park brake arm. To finally fix this I cut a piece of angle iron and ground it to shape. Then drilled a hole between the pedal and the arm and bolted it with a 1/4-20 bolt. I had to weld a small tab over the top of the arm so the pedal can't pivot.
Then I found Miket320's 's post about adding a grounding switch for adding a park brake warning light. Since I haven't had a P brake for 15-20 years I figured I was a prime candidate for forgetting it was engaged and driving with the P brake on. So I followed this post https://classicbroncos.com/forums/threads/brake-warning-light-emergency-brake-warning-light.263832/
Knowing that I was going to have to contort myself under the dash for an extended period of time I built a platform to lay on by using a step ladder and some wood planks. It really made it a lot more comfortable working under the dash that way.
I looked and my P brake assembly already had the holes drilled in it for adding a switch.
Bought a Dorman SW3898 $30 from Autozone and a 10 x 32 x 3/4 inch bolt to hold the switch on. I Had to use a philips head bolt because neither Home Depot or Lowes carries hex bolts that small and I just wanted to get it done. Of course I also had to tap the hole so I could thread the bolt in. But here's the switch all mounted up.
Even with my wood platform I couldn't easily get to the back of the ignition cylinder so I connected to the wire going from the warning light out to the brake proportioning valve. And now I have a functioning parking brake with a brake warning light that illuminates whether it's because of the P brake on or a pressure unbalance at the proportioning valve.
