Trying to connect a bill validator. Please help.

I have a Glassfront 3076 Model vending machine with a Coinco 9300 Series coin mechanism. I'm trying for the life of me to hook up a bill validator. I have a Mars VN 24 volt bill validator that I cannot get to work. It won't stop blinking double red meaning Disabled from Mech/Vmc. I read the manual and cleaned and filled the coin slots in the coin mechanism. The front display stopped saying "exact change only" after I filled the coins with quarters dimes and nickels, but validator still blinks double red. It won't even take a dollar and spit it out, it just doesn't do anything. Any help on how to get this to work would greatly be appreciated.
Questions
- what connection cables do I need? I have a Mars to Maka cable running from the validator and connect to two connectors ( one 6 prong and one 4 prong) to the machine. Is that all I need? There seems to be a spot on the validator to accept another thinner but longer plug. (Wish I could post pictures)
- is this the right validator? The manual says I need a 24 volt validator. That's what I have.
- what other things can cause the double red blink " disabled from mech/Vmc" to happen? The coin mechanism seems to be working properly as far as accepting coins and crediting them correctly is concerned.
- what should the dip switches on the validator be at?
Again thanks for your time and help.

While you might have the correct power connections to the validator from the machine using the Maka to Mars conversion harness, the VN2502/2512 won't communicate with your machine without a communication harness or a "snubber" plugged into the other communication pins on the side of your validator. In other words, this validator needs to talk to the logic board or think it's talking to it. Because there is no communication harness from this machine to the validator you must fake the communication with a snubber. The snubber will always enable the $1 accept line in the validator even when the changer is out of correct change and the validator should be disabled - the snubber will keep it taking bills anyway.
PM me if you need one and I'll see if it's available for this application.
