30' Mariah keypad
 

Traded in a 30' Mariah,sold it out of state,buyer just called and asked about a touch pad panel on the dash, he thought it was maybe keyless starting if you punch in a code. We ran the boat, it started fine with the ignition switch, I dont have a clue on this pad. Mariah is out of business,original owner is out of town,dont want this guy to get stranded. Any ideas?I just want to reassure him that there should be no problem.
