Facilitate the normal area of google searches, SVTP and Corral. I've been informed my fuel pump issues on this 99 to 03 cobra conversation maybe within the CCRM. I have several that I've tested but still can't get the pumps to turn on. I was informed that the CCRM needs to "match". What I can't find is WHAT does it need to match too? Since this vehicle isa conversation the HEC/Cluster, harnesses are all from different vehicles. Now the AC and Fans appear to work just fine with the various CCRM's I have, but it has been identified that when it comes to the fuel pumps I may need a "matching" CCRM. What I can't find is what is it suppose to match too? Just to place additional facts: Cluster is from a 2003 PCM harness and PCM from a 2003 cobra. Tank and pumps are from a 2003. FPDM is from a 03 or 04. I can't remember if the rear vehicle harness that goes from the FPDM and to to the Tank is the original 99 cobra harness or a 03-04. Though it appears everything in rear rear does work, lights, turn signals and such. Harness on the driver side going from the battery under the quarter panels to the firewall maybe GT harness from 2002. I say this only because it appears the connectors for the horn are different. At least for step 1 here I'm attempting to determine which CCRM I need.
