Engine keeps running without key???

[LowSL2]

So I have a 91 ECU in my 92 R/T. Today when I turned the key off and removed it the engine kept running and the indicator lights were on real dim. You know like when you turn the key to the on position with the engine off? It's almost like I'm getting some kind of feedback from something or a sneak circuit somewhere. Anyone had this before when using a 91 ECU on a 92 or 93 R/T?

It did it once so far. I did a search and found that someone else with a T2 was having the same problem when he switched from a 92 ECU to a 91. I have some 91 FSM's coming so I'll compare schematics. I was curious if anyone else had the same problem and if they found a solution.
