If the car was available as a T2 car, aka Lebaron GTC or Daytona shelby, then the turbor harnesses are all the same. The only difference is the CTS wiring isn't plugged in. On T1 cars it's tucked away in the harness. And if for some reason you can't find it it's extremely easy to add. Much easier than swapping whole harnesses out.
It'll probably plug in, But I'd be a bit leary as to the rest of the wiring. I say that because years ago I know someone that tried to put an 89 daytona harness into an 88. The headlight wiring was different that powered the motors, 3 pin vs a 4 pin. Also has a 4 wire O2 and I think there were a couple other small differences that made it a real pain. It's not just plug and play. I'm assuming the Lebaron is very similar in the changes they made since year for year the changes to the daytona seem to match the Lebaron.
