PCM wiring
i have put a 2013 5.7 in a 68 Barracuda. I have it all wired and attempted to fire it up for the first time today. The harness is from swap specialties....and before I even go farther, please do not buy anything from this company....please tell all your friends not to buy anything from this company. They are helpful until they get your $- then they are literally gone. The harness was just thrown in a box with zero instructions. So....the engine will crank, but it is using the old harness for cranking only (no connections from ignition switch to pcm, or pcm to starter at all). When the key is on, I get power to the coils, but the power cuts off during cranking. I get no power to the fuel pump (key on or cranking), (no issues with pump itself- I can jump it and it works fine). My question is what tells the PCM to switch on and power what it needs to during cranking? I’m missing some link between the old harness and the new harness and again, get zero support from that awful company. Thank you in advance for your help!! I uploaded a couple pics of the car...looking great, getting close!
