I reinstalled all of the engine wiring I had previously installed and then rmoved along with the engine.
Here's a selection of bits installed today.
Picture 1 shows the heater door I was working on yesterday before I was diverted from the task at hand. I have held the door shut with locking wire while the high temperature sealant between the door and the firewall goes off. I put lots of beeswax on the door so the sealant does not permanently seal both parts together. Fortunately it worked ;-) I eased a screwdriver into the gap and the door swung open. Success here at least.
Picture 2 (out of focus) shows the air filters I installed on the engine. I believe these may already be fitted on a "Vans" engine.
