I am working on a full wire tuck of the engine bay. I already have the body harness under the dash, but I want to move the PCM under the dash as well. There is a small hole in the very center of the firewall where the HVAC ducting was mounted too. Should I open it up and slip it all through there? How has everyone else done it?
