Dakota Digital 2012+

I have a 2013 Tacoma 4X4 V6 , 33s with 4:56 gears

I bought a Dakota Digital SGI-5 to correct the speedometer & odometer.
Searched and searched for hours and days on a write up for 2012+ wiring colors and locations to no avail.
I read "Finecamaro69s" thread but he has an older model.
I would like to avoid pulling my gauge cluster out .... future Rattles
My question is where can I tap into the ECU output to the speedometer ?
Where is the wire harness bundle ? and what wire am I looking for ?
I would like to mount the SGI-5 behind the coin box , or whatever that useless box is called .... I'm gonna make it useful
I hope someone spots this and can help
Please be specific and include any pics
I'm search Frazzled !
Please don't refer me to a thread that shows hook up on a older than 2012 model.... I've already read it 10Xs
Thanks Guys !

 

Hmmm , nobody with a 2012 + used a DD to correct there speedo ?
Confirmed .... I'm weird

 

No idea how to wire up the DD. But I have a 2012 and 33's. I'm only seeing a 2-3 MPH difference in my speedo reading and my GPS @65mph.

I only mention this because that slight variation falls within acceptable limits of any manufacture for speedo accuracy.
