 The spec sheet says that a 10K pot goes accross pin 2 ref and ground /case pin 5 with the wiper to pin 1 
Of coarse you need bypass caps  and a small choke in series with the supply.  should work.

 Hi all:

Will anyone help me with the pin wiring, and needed componets ( values ) to use an Isotemp OCXO 131-191 ?

Pin-1 = V ctrl
Pin-2 = V ref
Pin-3 = +VDC ( 12 V )
Pin-4 = RF Out
Pin-5 = GND

I will use this to replace the Xtal Osc on my 630 meter Transverter. Thank you, and 73:
