Buddy is selling his '01 LB7 and he said I can have his CTS Insight if the dps5 switch works. I believe the truck has Idaho Rob tunes if that makes a difference. Is there anything special I need to do to get the switch to work again? I unplugged the CTS and the switch didn't seem to do anything, I then read that if the CTS is unplugged it defaults to tune 3. I checked the ECM connector, and the switch wires are still hooked up, haven't tested the switch for voltage yet. Thank you in advance for any help.
