Any TYM dealer should be able to sell you the kit. The dealer can install it, or you can do it yourself. It's basically just another valve to go in the stack, longer bolts to put your new bigger stack together, and the lever/linkage to the cab for the new valve. You could also cheat and use a hydraulic multiplier with three sets of ports (or more if you want) leave your top and tilt plugged into that, activate them when you need to make an adjustment, and still have both remotes available whenever you need them. Another sly idea is to get the third remote and put a multiplier with two sets of ports off of it, giving you a dedicated top/tilt control lever with a button to swap between the two.
