Sun Coast Loc-Up Controller

[RSWORDS]

I'm doing a 47RH swap into my 89 Cummins this winter. Instead of using switches and what not to control OD and TC Lock-up I was wondering if this would work.

The ony problems I see are that I dont have a VSS or a TPS. Will this work as a stand alone controller in my application?
