Back to work on the firewall. My shipment of hardware arrived and I was able to get the proper sized bolts for the solenoids and coolant tank bracket and mounted them. I also picked up my bracket that I made for the waste gate servo that I had polished. I drilled out the rivet holes, cleaned everything up and riveted it to the firewall. Lastly, I drilled out a 2.25" hole for the ECU cabling. I had to go that big in order to get the terminated end fitting through the hole. There were several other plugs and relays attached that needed to pass through as well. I've deburred the hole and have some gorilla tape on it temporarily to protect the cable. I will fabricate a cover for this hole that will neck down to the cable size you see in the pic. I have at least two holes left to drill, for both fuel supply and return lines with perhaps one small hole for sensor cables. Not sure about that yet. I'll probably mount the engine to verify all that I have done and make some decisions about the next holes.
