Hi,
Okay, I attached two pics below to help. Power comes from the powertrain relay in the under-hood fuse box. Once the relay is actuated, power travels through the injector 1 fuse and to all fuel injectors via a pink wire.
Each injector will have two wires. One on each is pink. The second wire changes from injector to injector. The second wire runs to the powertrain control module (PCM), each to a different pin. The PCM then provides a ground path to complete the circuit one injector at a time.
Let me know if that helps or if you have other questions.
Take care,
joe
See pics below. I highlighted all relevant wires.
