I converted my Anycubic i3 Mega-S to dual extrusion, and I was originally working on a guide showing exactly how I did it (since the way I did it is different from what I've seen posted already) but.... an entire guide is a lot of work and I'm not sure I'll get around to it (EDIT: June 18, 2022: I've now added a mostly complete guide) . Until then, I'm just going to post this stuff separately in case someone can make use of it.
I bought a cheap MK8 extruder designed for a CR-10 from Amazon, and I used these pieces to mount it to the left side of my Anycubic i3 Mega-S. I've included two files to attach the motor/extruder itself, as well as some clips and a wire track that allows you to run the wires down the side of the frame and still have it look decent. See the pictures.
These are the parts I used:
Twotrees Stepper Motor Nema 17 Motor High Torque 1.5A (17HS4401) 42N.cm (60oz.in) 1.8 Degree

Anpro MK8 Extruder Aluminum Alloy Block Bowden Extruder 1.75mm Filament for Creality 3D Ender 3,CR-7,CR-8, CR-10, CR-10S, CR-10 S4, and CR-10 S5

Note that the extruder pack I bought no longer seems to be available, but if you do a search you'll see there are many companies selling what looks like exactly the same one and they're all fairly inexpensive.
