I wasn't sure where to ask this, but hopefully someone here can help.

I have a Liberty bar. It used to have a LFL controller in it and I swapped it for a LC controller and hooked up a MPC03. The MPC03 I got has a button labeled as Cruise. I'm using the SC Programmer software. The software has a checkbox for Cruise Lights when you're configuring the bar. However, I can't figure out how to make the button turn on cruise lights. There's no option for steady on (or anything like cruise) in the corner lights dropdown, only for the LEDs (the rest of the lights). Am I missing something? Has anyone configured one of these for cruise lights? I had the wire for it on the LFL controller and used to have it come on with my parking lights.

It's interesting that the control head has a button labeled as cruise as well, because when I read the configuration it was previously used with a Liberty bar as well. But, when I hooked it up without reprogramming it, I couldn't get the button to do anything.

Any insight on this would be appreciated.

Thank you!
 
Your post is helpful, and thanks for all of the information. I noticed what seems like a contradiction though. Can you please clarify whether you have an LC (low current) board or an SC (serial control) board, also known as B-LINK, installed in your Liberty?

I've never had a B Link Liberty with Cruise... that's several vehicles over several years, probably 2005 - 2014? My LC has Cruise, but I don't know what year that is.
Best you could do was Steady, but that was only an option for the inner heads ... and then that would be applied to all of them.

So, the two inner Driver Red would be Steady 100, and the Arrow set to Flash (it overrides, and is independent) ... did some Pursuits like that.

The BL10K had Cruise, but it only activated an plug output.
