[urq] knock sensor unit on WR engines?

[Justin]

Hello all, 
I'm currently trying to implement a knock sensing unit on my WR engine...(cause I plan to make some mods, and I want to keep things safe...).  The cheapest way I can see to do this, it to use the knock sensor and knock sensor unit from the 85-87 4k 4cyls. 
Could this be done safely, without conflicting with the normal timing operation of WR ignition control unit?

Any thoughts or advice are always appreciated, :)
