Brake Switch Wiring Direct Off Battery?

[central52]

I've looked at some posts about this rewiring, but how does it exactly work?  There are two wires coming off the switch.  Now where do you connect them?  Are there any pics on this procedure?  Ed

the schematic is not very clear on this for the P15     but the lighting section will explain that the power comes from the protected side of the main lighting fuse/breaker..is hot..shares power with the dome lights..is always hot on the one side of the switch...switch cares not which leg is hot as long as there is power on one leg and it will connect with hydraulic pressure..you should get power to the stop lamp, this is the second wire on the switch..and leads direct to the stop lamp socket..

I have attached a schematic with the brake light system marked with red. The red X's identify the wires and the components they connect to are circled in red. Hope that helps.

Excellent timing on this question. I'm working on my brakes and just got a new switch and was wondering about it.

I did this change a couple years ago.  Determine which wire is the feed to the switch, a simple circuit tester probe works.  Wedge the brake pedal with something between it and the seat cushion. Then use your circuit tester to find the hot wire on the switch.  The wire to the lights will not light the circuit when grounded and disconnected from the switch, the power wire will light the probe.  Reconnect the wire to the lights.  Then make up a wire with an in line fuse holder ( I used a 20 amp fuse) long enough to go from the battery side of the starter solenoid to the brake light switch, and connect that to the other terminal on the switch.  Crimp on or solder on connections can be found that are appropriate to the connections necessary as the switch terminals seem to have changed over the years.

Thanks, guys, for the info.  Ed
