I have an '02 ranger and I've installed power windows (working perfectly), power mirrors (just installed today and working), and i've installed power lock accuators and OEM switches, but now i'm stuck because I can't find the CSM that the OEM accuators and switches need to go to. I've pick up a ford wiring diagram for my '02 and shows the CSM behind the dash, behind the passenger airbag. I have my airbag out and glovebox out and i'm not seeing anything. Can someone please advise me where to look.

 

That's the correct location. If your truck was not equipped with power locks and RKE from the factory, then it did not have a CSM.

If you had one, it would look like the whitish module in these pics:
