I don't have a Rescue 911 in front of me, but this is one of the 'gotcha' places in pinball.
Any wire tie that is close to where the wire wants to pivot, if you make it tight, will bind and eventually break the wires - inside the insulation -.
The usual symptom is to have an intermittently working helicopter (grabber coil or motor) and you tug on the wires and they come apart right at the wire tie... because the copper strands were already broken!
So, while I don't have a diagram, what I do is get a real feel for how the wire pulls, how it moves. Then I put black wire ties, but I leave the loop really loose, more of a suggestion than a binding wire tie wherever I can. Like a half inch circle in the wire tie. Then after I've put a couple of wire ties on the helicopter wire assembly I'll tighten a few of them slightly to make a smaller circle. My goal here is to have that wire be able to move where it needs to, but get the wire to where it's length doesn't cause a bind.
It's more of a 'do this by feel' thing than a 'do it exactly this way'.
(shrugs) Get it wrong? No biggie, but you'll have premature failure of the helicopter. For this assembly, you are likely to be replacing the wires to the helicopter a couple of times through the years if the game gets played a lot. It's a common failure, so don't get worried about it. Just know that you'll have to fix on this eventually even if you do the best job possible on looming this wire.
Sorry I don't have pictures!
Good luck!
