Icon4 Fuel injector wiring

Got a question for all you engine rebuilders, I recently rebuilt my 2000 ranger 3.0 and I'm in the process of putting it back together, but I can't remember the wiring for the injectors and was stupid and didn't take any pictures, my question is does anyone have any pics they can show me? Also are the connectors for each injector on the wiring harness? Or are they individually wired, any explanation is appreciated!

Yes the injector connectors are on the wiring harness and each injector has 1 wire that runs back to computer, IN the harness, and 1 wire that is shared, 12volt wire, it is daisy chained from one injector to the next, IN the wiring harness.

Wiring harness will only go on the engine one way, that should lay out on it's own but if you find a wire doesn't reach it's connection then it is layed out wrong, don't pull on it, find out why it is short, maybe run harness under a part rather than over it.

Thanks for the advice! Wouldn't happen to have a picture would you? I get what you're saying but just can't seem to picture it in my head. Thanks in advance

A picture of what?

On a V6 the intake wiring harness "usually" runs from firewall forward on one side then loops around the front of the upper intake and back down the other side.

This harness will have sensor and control connectors and the 6 fuel injector connection, 3 on one side and 3 on the other.
