1972-up ECS hoses connection

Hi guys

I envisage to upgrade my '71 /6 Demon ECS to the more efficient '72-up charcoal canister ECS, but what's the correct hoses connecting..?

Chrysler #4723551 :

The 1972 FSM doesn't really help as the charcoal canister hasn't the same design and color coded nipples
