Coyote electrical

[Tbev]

Hi all,
I know there are many threads on this topic and I have read many of them and I am still confused. I have a roadster with a gen 3 Coyote. So here are my questions:
1. I have the battery positive lead going to the starter and then from the starter to the fuse on the firewall. Can I connect the other 3 starter wires to the fuse stud instead of at the starter?
2. I prefer to wire the starter as Ford Performance intended. With that said, does the light blue wire in the harness leg with the 3 starter red wires go to the starter and not get cut off as the FFR instructions state?
3. Does the starter solenoid wire get connected to the same stud on the starter as the light blue wire (if used)?
4. I am using the neutral safety switch. What other wires do I need to connect on the dash side?
I apologize for the rookie questions. I have thoroughly enjoyed my build up to this point. Wiring really stresses me out and I find the FFR instructions confusing and not very clear.
I appreciate any help.
Tony

Based on the questions you've asked I wonder if you've been using the general FFR roadster instructions instead of the coyote specific instructions. Here are the two main documents for a coyote based build:

https://performanceparts.ford.com/download/instructionsheets/FORDINSTSHTM-6017-M50BA.PDF

Regardless, let's go over your questions since I believe it will be helpful one way or another.



1. I have the battery positive lead going to the starter and then from the starter to the fuse on the firewall. Can I connect the other 3 starter wires to the fuse stud instead of at the starter?

Two things to consider here:
Is the wire from the starter to the fuse the same gauge as from the battery to starter? or in other words is it capable of carrying the current required by the 3 starter wires? If so then there shouldn't be a problem with connecting the 3 starter wires to the starter end of the fuse. As for the fuse, are you referring to the 250A mega-fuse that came with your coyote? Ford says to only use that fuse to guard the coyote PDB. Most of us have been scratching our heads on how the heck ford control pack could possibly pull that much current, but Ford says to do it so we did.



2. I prefer to wire the starter as Ford Performance intended. With that said, does the light blue wire in the harness leg with the 3 starter red wires go to the starter and not get cut off as the FFR instructions state?
I believe the FFR's coyote specific instructions say to reroute the blue starter wire to the coyote control pig-tail. See page 96 of this document: https://www.factoryfive.com/wp-content/uploads/2020/03/Coyote-Gen-3-Fitment-roadster-rev-1B.pdf
You do NOT use the RF harness blue wire to power the starter. The coyote setup has the starter controlled by another wire from the Ford Control Pack.



3. Does the starter solenoid wire get connected to the same stud on the starter as the light blue wire (if used)?
Are you referring to the starter solenoid wire from the ford control pack (black wire IIRC)? That wire replaces what the blue wire does in a non-coyote build so while the light blue wire does not go to the starter solenoid, the one from ford control pack does.



4. I am using the neutral safety switch. What other wires do I need to connect on the dash side?
Here I assume by "on the dash side" you mean "everything not in the engine bay". If so, yes. You need to do some alternate fuel pump and starter signal wiring with the coyote pig-tail, the RF fuse-panel's fuel pump power, and perhaps more that I can't recall. I recommend reading ford's instructions on coyote installation https://performanceparts.ford.com/download/instructionsheets/FORDINSTSHTM-6017-M50BA.PDF especially point 6.0 which details how to signal the control pack for ignition and start.

First, Thanks so much for all of that information. It definitely clears things up for me. To answer the above questions, yes the gauge of the wires going from the battery to the starter and starter to the fuse are the same. And yes, I was referring to the fuse that came with the Coyote.
Thanks again.
