Cruise switch question. Switch link

[Mike H]

I have a switch link box for the cruise cancel button to actuate a 12v relay. I am needing 2 more switches to control Trans brake and boost scramble.

Question is do the cruise "set" and "resume" switches send the same signal as the cancel button? If so I can simply purchase 2 more switch link boxes. If not has anyone found a way to use them?

Car is a 4l80 so the cruise is inop anyhow

Thanks in advance!
Mike
