We are replacing the fpr in the truck. We have the California emmissions package on the truck and a nice black wire harness case running in front of the turbo horn and behind the alternator from the ecm on the passenger side to the rear compartment of the driver side. How do you get the pos out of the way to get to the cp3 to remove the fpr? The harness connectors left attached are to the ecm and on the bottom of the engine compartment and still can't get it out of the way!! Suggestions?
