Trim oil cooler for more engine mount clearance.
Reinstall oil cooler. Tighten oil hoses.
Install new ground cable. The new arrangement has the battery grounded to the engine, then the firewall to the engine. This prevents forgetting to ground the engine, which is exactly what I did for the recent tech counselor visit. Deene pointed out what would happen if I tried to crank the engine like that - all the starting current would have to flow through signal grounds, which would fry, along with the tranducers.
Start trimming lower cowl for fluid pass throughs.
