Ford 9" And Separate parking disk brake question

I recently picked up a ford 9" and converted it all over to fit my 02 tacoma. I have wilwood brakes (not the parking brake combo) on it but no emergency brake. This is my DD and before i swap the 9" in i have been looking into options to run a parking brake to my stock lever in the cab. My question is has anyone ever done this? i searched all around and couldn't find anything on it.
I found these http://www.jegs.com/i/Wilwood/950/120-12069-BK/10002/-1

It dosnt appear that anyone sells a cable kit that will work for what i need and im assuming that i cannot use the existing cable system on it, so is it possible to do this without breaking the bank to much and what are suggestions you guys might have on doing this.

 

You're probably better off buying new calipers that have ebrakes in them.
Versus trying to retrofit something else together.

I converted to discs on my jeep Dana 44. The calipers had an ebrake setup on them and I connected it to the stock OEM cable system. Granted, it took a bit of time to get it setup properly (cable tension, etc).

Or, you cold investigate a driveline ebrake setup - usually they attache right at the tcase.

 

There are drum-in-hat rotor options to fit the 9"

A few marques have a rotor with a 'hat' in the center that is actually a small drum. Pulling the rotor exposes a small set of shoes that function as the ebrake, activated by a manual cable. This has been around since at least the mid 80s.

Poking around on some street rod/hot rod web sites will bring up with something for you, as the 9" is so widely used there.
