I have a gen 2 coyote donor for my roadster and there are so many hoses on their. How do I know which ones I have to keep and the ones I can remove or cap off??

Really hard to give a specific answer. Most, including me, have used the crate motor and control pack, so likely differences. The short answer is probably most are required. Modern engines like the Coyote have a bunch of hoses and harnesses that have to be there. FWIW, the Factory Five Coyote installation manual for that version may give some guidance. https://www.factoryfive.com/wp-content/uploads/2019/07/Coyote-Fitment-roadster-rev-2B.pdf.

Thank you, I am also using the control pack but as I was taken off the air conditioner I was trying to figure out what other hoses to take off. I appreciate the PDF file

On page 59 of the coyote installation manual it shows connecting the CMVV vacuum hose to the inlet tube. Some have said it needs to be connected to the a vacuum port behind the throttle body. Does it make a difference on what year your coyote was manufactured to where this line is connected?

Yes, there are two versions of the Gen 2 Coyote for the CMCV connections. Early versions were vented (not vacuum) to the intake. Later versions eliminated that hose and they vent to atmosphere at the back of the engine. Both versions require a vacuum connection, typically along with a "T" if you're using a fuel pressure regulator with a vacuum reference signal.
