So I’ve recently ran out of things to tinker with on my truck.
Had the idea of hooking my aftermarket Rostra Cruise Control up to my factory switch instead of using rostra’s 250-3592 Open circuit switch.
Both switches are 4 wires. Rostra is setup this way
factory switch is setup this way
my idea was to cut the wire before the clock spring and connect the 4 wire pigtail from the Rostra cruise. Unfortunately my 2nd grade electrical skills aren’t sure if it’ll work.
Rostra is a normally open switch, I’m not sure if the factory switch is open or closed.
Speaking with Rostra, they say the red is constant power from brake switch. Brown is on/off.
there are 4 wires on the factory switch and 4 wires on the Rostra harness. According to the Rostra wiring diagram red is brake hot and brown is positive brake.
Im using the 94/95 cruise control switch with off / on / resume accel / set coast
