Retro Fit Cruise Control.....

Got access to and anytihng I want from a 94 RRC going to the big crusher int the sky.... so far took a few bits I needed for mine but interested in retro fit of the Cruise control... I have the switch steering wheel and vaccum thing off the throttle and pipes + brake switch, shave the AMR2009 ECU and the whole loom is coming out so I can have what I need.

Is there anything that 100% will stop me retro fitting this to my 91 3.9 ???

Vacuum Pump???

If its on the outgoing motor with Cruise on I will have it....
All Hardware is available and most is now with me just the loom and AMR2009 ecu I was waiting for....
