I have a 1998 isuzu rodeo 3.2l V6 4WD 5 speed manual trans. I had installed cruise control in my truck from parts i got from the junk yard.The connection points were already there from the manufacturer on the wire harness. I installed Steering column switch for Acc, resume. etc. Also installed main switch on the dash and the actuator in the engine compartment for the throttle control. I took the parts from a 99 isuzu rodeo with an Automatic trans it also had the 3.2l V6 same as mine. All the parts have been tested. I found no dedicated fuses or relays on my truck or the 99 i had gotten the parts from. The center console of the 99 had a gray cruise box. My truck does not have it or the connection for it. I was made to understand that my truck cruise worked off the ECM and actuator. I looked all over my truck and can not find the connection point for the cruise box. My cruise does not work. What am I missing.?
