JEEP GRAND CHEROKEE COMPUTER LOCATION

I'm Trying To Find The Ecu / Ecm. Research Goes To Pcm When Googled.

Where Is The Fan Control Module Located? Cannot Find It!

My Jeep I Bought Few Months Ago Needs The Wiring Harness For The Pcm Replaced For An Issue With It Stalling And Backfiring While Driving....

Where Is The Pcm And How Do You R&r It
