Emergency Brake Switch

[72_K10_Vegas]

Gents,

I have a 72 K10 and I am using the Dakota Digital VHX system. It has an input for the emergency brake being set. I am wondering if our trucks came with that option or if anyone has installed one. I found a couple of threads but they were on later model year trucks.

I certainly can fab a bracket and purchase a micro-switch, but was wondering if a switch was factory made for the 72.
