Replacing Maka Validator with Mars in Crane 474 Combo

[Vending by WC]

Hello everyone, I'm replacing an old Maka VFM validator with a Mars 2500 series in my Crane 474 combo. Long story short, it was accepting cash but not registering the credit. The validator-to-control harness also turned out to be bad, so having to replace that as well.

I thought I had purchased everything needed for this upgrade. A new Mars validator, a Maka-to-Mars conversion cable and a validator-to-control harness that D&S sells for this machine (supposedly meant for Mars dbv's). But when installing, I realized that the power connection on the validator-to-control harness wasn’t compatible with the validator or the conversion cable (2 males). The new validator harness fits into the board just fine, but the only other connection that fits is the one that plugs directly into the side of the validator itself. The maka-to-mars conversion cable doesn’t seem to fit anywhere. I’m posting this with the hope that someone else has gone through the same upgrade and can offer some direction as to what I’m still missing. I’ve attached photos of the previous setup and the new setup that I’m trying to make work. I can also provide links to those specific products if the photos are unclear. Any guidance is greatly appreciated.

If you're simply replacing the Maka, leave the original MAKA pulse harness in the machine and use the MAKA - Mars conversion alone.  Power, enable and credit all happen down that harness.   You have it all ready to go in the 2nd picture.

Unfortunately there is a problem with the old pulse harness too.

That being the case, either repair the original pulse harness or source a MEI power harness for 115 VAC application.  Then you'll be able to use the other rig.

Thanks, I'll look for the MEI power harness.
