Has anyone seen a write-up on an install for the Mark's 4wd speedo correction. I DID search on here and Slee's site and have not found anything. It's a fairly simply install, I was just curious where you guys mounted your conversion box and where/if you drilled a hole in your tunnel. Someone had mentioned that you could use an existing hole or rubber plug??? Anyhow, thanks for the help.:beer:
 
You can download the instructions exactly as they come with the unit from Slee's site.

There is indeed an existing rubber plug in the tranny tunnel on the US Passenger side up under the center of the dash. Pull back the carpet and you'll see it.

The unit is truly plug and play and works great.

Ted is correct. I ran the wires through the rubber hole as well and it is one the few actual Plug and Play mods. Works great, the hardest part was finding where to mount the box. I ended up putting above the hole with zip ties, it's out of the way and no holes needed to be drilled.
 
Cool. I'll give it a shot soon as I get home. I heard nothing but good about this product. What tire sizes are you guys running?
 
33's with 4.88's.
 
I ran the wires thru the rubber plug on the passenger side and mounted the unit vertically along the front edge of the center console.

Good to know!

Thanks!
