Brake light switch issue
I just bought and installed the Painless wiring torque converter lockup kit, part #60109. The kit suplies a brake light switch, but there is no way to use the brake light switch with my application, any ideas? BTW, its a 4 prong.

Re: Brake light switch issue
i looked up the manual on painlessperformance.com, if your using the stock pedal and switch it will be difficult to install a different switch.
currently you have 12 volts to the brake light switch, when you push the pedal the switch makes and you have power to the brake lights. from the painless manual for your part: THE TWO TERMINALS CLOSER TOGETHER ARE FOR PASS THROUGH VOLTAGE AND THE TERMINALS FARTHER APART ARE FOR BRAKE LIGHTS. their switch is a PDST (double pole single throw) with NO/NC contacts with the pedal up you need 12 to the trans and not the brake lights with the pedal down you need no power to the trans and 12 to the brakes you need a relay. a simple bosch type relay that you can buy at any parts store courtesy of the12volt.com keep the existing switch and wire to your brakes and then add everything below using your 12v feed into the brake switch splice a wire to also feed terminal #30 run the purple wire from the trans to terminal #87a hook the one side of the coil to the brake light (switched) side off the brake light switch and the other side of the coil to a ground this should give you 12v to the trans when the pedal is up and no power to the trans when the pedal is down

Re: Brake light switch issue
Thanks for the help, that makes everything different! I had no idea wtf I was going to do, as there is absolutely no way to mount that switch!

Re: Brake light switch issue
I take it your using the stock floor mount brake pedal.
Check with NAPA they may have a switch that is the same style as the stock switch but is electrically opposite. If they do, mount it like the stock switch and wire it like the above. Two switches one job. |

Re: Brake light switch issue
I am going to use Ogres idea, far easier than wiring in another switch!

Re: Brake light switch issue
Not trying to hijack the thread. I am considering the painless kit but also the tci kit that uses vacuum. Have you heard that one is better then other. I would like a manual override with either kit I used. Besides the brake light issue how did the rest of the install go?

Re: Brake light switch issue
Both kits are the same thing, they both come with a vaccuum module that plugs into the trans. Real easy instal...except for the brake light switch, but I will update you on that sometime this week. Instructions are very detailed and do not leave you guessing.
