561t dei old style dip switch settings

Hello, I have an old 561T I ripped out and replaced with a combo unit. I want to reuse it. It has no layout on the back (OLD OLD 94-95 unit) -- I know one was for cylinders and one setting was for tachless mode. Does anyone have an old manual or remember what the dip switch settings are?

I don't believe the 561t is that old. It came out sometime this century. The 551t was the older version of the 561t. I don't think that unit had the dipswitches either. Can you verify the model number? From a Viper 550HF that was out about 1995... dip switch          ON position   OFF position 1          Zero Cylinder             Tach Input connected 2 Parking lights constant        p. lights flashing 3           12 min runtime 24 min 4        Learn tach ON             Learn tach OFF

Just wanted to say thanks, you are correct. You jogged my memory now, it is a 551t. Hard to remember 14 years back!
