Parking Brake switch

[hakukamana]

Looking for a part number or a source for a parking brake switch. Looks like the OEM number is 56001966 but as usual discontinued. Its got to be a GM part for late 80's GM vehicles. NAPA shows nothing, along with AZ, and O'Reillys.

You could try looking at GM trucks but my best guess is the parking brake is an AMC built set up and not a GM. If it was a GM truck I'm sure someone would have piped up and said something by now. Whats wrong with the switch currently?

The contact tab that engages the switch when the brake is applied,  the lower section of the tab appears to have snapped off. This is probably the original switch to the truck, the part number on the switch is 8956001966. There are a lot of similar designed switches out there but the closest one that I found was TLS300, its a Echlin part number "NAPA" not exact but pretty close.

The solution is not an exact replacement but, fits the location, functions just like the factory switch and is only $10.00. NAPA part number PB4016 fits the requirements for the Comanche parking brake switch, the only difference is the position of the brake light tab. The tab points down and points to the rear of the cab, the factory switch tab points up and to the firewall.

Would you recommend such for others or nay?

I spent more time going to NAPA and buying it, than the installation of the switch. You do need to reroute the brake light switch wire between the hood release cable and the brake assembly but not a big deal. If you need a switch, which I did, "safety check", if the light no workie you no pass the safety check. I would say yes its a good choice. I'll take a pic tomorrow and post it up.

Sounds good. The pic would be worth to see!
