n00b question... wiring up my ignition switch, red, orange and blue are easy...
but the brown ACC and Alternator-IGN I have the question...
the RF Manual (Rev W) shows
Attachment 152286
I'm installing the Gen3 Coyote with the M-8600-M50BALT Alternator Kit
unsure if the alternator is a 1-wire or 3-wire?
my assumption is 1-wire, but figured I'd check with the forums before I cover it up
No. The brown alternator wire is not needed for the Coyote alternator. That's an exciter wire used for one-wire alternators. Not needed for the Coyote's 6G alternator. I remove it completely. The control pack does have a connector that plugs into the alternator because it's actually controlled by the PCM. There have been discussions in other threads, including recommendation from a tech at Ford Performance, to leave the plug disconnected. That's another discussion. I personally leave it in. You will notice the Coyote alternator will show higher than you're probably used to charging voltages. 14+ volts on your gauge. It's normal in my experience and based on what I've heard from many others including Mustang owners.
Thanks Paul - always a fount of knowledge!!Quote:

I'll keep the control pack info in mind, my Coyote should ship out Friday - getting close!
