2007 5.7 Hemi in 73 Plymouth Duster (pedal cuts out)

Swap specialties harness worst harness ever!!!! I wouldn’t even be surprised if I had more wiring issues but I think I checked all the trans and sensor wires for speed so idk? Blake from diy hemi says maybe I have a short? Maybe in the pedal? I am using a 05 hemi 5.7 545 rfe 05 computer but ecu was 4x4 so I think it had extra wheel speed input but said it was all the same when I got information from what I thought were credible sources
