I removed the old HIC module after moving the ECU out of the way yesterday. Then I clecoed and screwed in pace TOOL-00114, which is, basically, a drill guide. That done, removed the guide, then filed the holes a little bit to get the new HIC module -- now known as AV-600009 -- to fit in the slots. I have not yet screwed it into place.

The next step will be to disconnect the old wires from the old Molex connector and insert them into the new connector. I think that maybe gets done before I screw it in place but I didn't have heat on in the hangar today because that kerosene I'm using is really dirty and I didn't feel like breathing fumes today. And it needs to be comfortable to do some wiring work in confined spaces. Maybe tomorrow.
