The last couple of days I installed the radio, Transponder, Compass, and the I ran the leads for the EIS through the Firewall by drilling a 7/8 hole through the F/W and inserting a 3/4" grommet in its place that will be covered by a heat sealed and silicone putty when done. Then I ran the 6 EGT and 6 CHT wire sets through the grommet also ran the wires for the oil temp, Oil pressure, and fuel flow. Installed the EIS display and wired the EGT probes to the EIS. Covered wires with anti chafing tubing that should also help keep it nice and neat. I had to redo some of the EGT end connectors as they were not attached well to the EGT probes. Installed connectors to the EGT leads from the EIS.
