Cut a hole in my left avionics tray to allow the EGT/CHT and Engine Thermo wires down for the firewall pass-through on the left side. Final mounted the Backup Battery and Engine monitor box on the tray as well as the ACM. ACM might need to come off as it is blocking access to one of the adel clamps needed to secure it to the tubing. AP harness wires are all laid out, just waiting to decide on the final/exact routing then cut to length and install the D-Sub. Installed the CHT probes
