Y harness help

Could someone link me the parts, except for the Traxxas connectors, that I would need to make a harness to charge 2x 2s2p 8k SPC lipo packs on a Hyperion EOS0606i charger so that I can charge it as one 4s pack.

I know that the SPC LiPos use different taps than the TRCs that I was running and I had made a harness to use on the said charger, but I deleted my bookmarks and don't remember where I ordered the pieces from.

The reason that I ask is that I am cheap and don't want to pay for a DUO charger if I will never be charging anything over a 4s pack(2x 2s2p packs actually). I would prefer an AC/DC charger so that I don't need an external power supply.

If you can give me a better charger for less that will work, let me see it. (Sorry for being all over the place, to many percocet today... lol)
