Hello everyone. have a Morex 3688 case and it looks like the dc power plug it has built into the case accepts a plug with 3 contacts (IGN, PWR, GRND). I've looked around google, and digikey.com but cannot seem to find where to buy the correct plug. Does anyone know where to buy this type of plug (DC power plug with 3 contacts)? Thanks in advance for any help!
