Power cable for A1451

I am installin the audiobahn a1451 in my vehicle. the a1451 comes with an 8pin DIN cable that connects to head units that have cd changer controls in the Sanyo format(Sanyo, Audiovox, Audiobahn, & Jensen). there is a cable that is available that plugs into the a1451 and has a filter/fuse box & 3 wires(12v+, 12v Acc, & ground). I am trying to find this cable. Audiobahn has not been any help because the unit is discontinued. if this cable cannot be found then will it be possible to cut one end off of the supplied DIN cable & wire it up to operate the changer, & if so what has to be done. in the supplied instructions for the a1451 there shows 4 ways to wire up the a1451. 1 shows the unit using an FM modulator. this is not an option for my install because my head unit(Valor DTS-660wt)has Aux inputs and multi-zone function. this is why i am using the a1451, for its multi-format disc reading capabilities. 2 shows the a1451 using the supplied 8pin DIN cable. again not an option because i don't have a Sanyo formated head unit. 3 shows the a1451 using a cable that has 8pin DIN on one end & 3 power wires (12v+, 12v Acc, & ground)on the other end. this is the cable i need. 4 shows the same as 3 but using an optical cable to send the audio to an amplifier with Dolby digital decoder. any help in either finding this elusive cable or a solution on powering up the a1451 would be greatly appreciated.
