Update: See post # 19 for specific upgrade wiring info.

I started pondering this when I recently started to put together an updated parts shopping list for the engine swap. Bear with me on this one. It's been decided that the car will definitely get a fast glow upgrade, but this isn't a simple upgrade.

The car: '77 300D, OM617 (Loop style plug setup)

The replacement motor: '83 OM617 (Pencil plugs setup)

The way I see it, I apparently need to buy the fast glow kit for the loop plug cars that includes four fat pencil plugs that I don't need, and then I have to buy five new pencil plugs that fit the '83 motor. Fun. I'd really rather not buy a kit that includes the fat loop to pencil plugs and jumper wires if I don't have to. Sadly, that might be the only way to get this done.

I do have the the entire '83 donor car, just in case anyone wants to tell me that wiring up the later pre-glow system in the '77 is something that isn't too involved. Maybe someone has done it? I figured that this was a question worth asking before I buy parts that I have no use for just to get the parts that I do need.
