So heres what Ive found out so far...apparently this distributor setup was used on certain 81-83 ford vehicles that had EEC III. One type was for carboreted models and the other type (this one) was used on vehicles that had Ford's central throttle-body fuel injection system. I know Chevy had TBI, but cant recall ever hearing about Ford vehicles having it. Anyone else have any input on this??
Ford used TBI on a few, plus a couple feedback carb systems as well. Lincoln Mark, T-bird 5L, Mustang 3.8L, F150, 5&5.8L ect...
Some of them used an early attempt at "distrbutorless" ignition, They still had a distributor, but all it has in there is a shaft and a rotor, no pickup or advance mechanisms. The earliest I saw was a 79 Lincoln Town car with TBI and that distributor. Most of them got replaced with carbs and duraspark3 up here.
I believe that's what you have there. I've never had one apart and I haven't seen a live one in 30 yrs.
I see there is no center electrode to connect to the coil tower, could you post a pict of the cap and wires?
Just curious now.
Cheers
