All, I just written up how to get a Tach Signal from my Coyote crate eng and ecu/pcu on my build page ('35 truck)

It's at the bottom of page 7.... link: https://thefactoryfiveforum.com/showthread.php?44055-Mark-s-35-Truck-Build-Extended-w-Gen-3-Coyote/page7

Nice work. Just to be clear, with Speedhut gauges it's only necessary to tap one of the coil packs and no adapter is required. Other brands, e.g. Autometer, require an adapter like you've documented here. I saw a question to Ford Performance in a Mustang swap forum asking why they don't have a tach out for the control pack (like GM does for the LS control pack) and didn't see an answer. We're not the only ones dealing with this. Oh well. Another FYI, you can link directly to a specific post. Go to the post and right click the post number. One of the options in the dialog box is "Copy link address." Click on it. Post this URL into your post and readers will be directed to that specific post.

Thanks Paul for the tip: i.e, post link URL option. Pretty slick and prevents the entire thread page showing up!
