I've tryed this before.Didnt get much.Got a donor 85 305 ccc berlinetta and a 85 sports coupe as the recipeant.the s/c was factory v6tpi.if I use the ecm and engine wire harness what will work on my dash and other stuff and what wont?I'm not really wanting to put the berli dash in my s/c

 

I'm not completely familiar with the digital dash, but I don't believe the controls go through the ECM. So, the only thing that wouldn't read right would be the tach.

 

the sports coupe dosnt have a tach on the cluster I got.What ya think about the speedo working right?The v6mpfi would have had a machanical type if I'm not nistaken.This car didnt have a tranny or engine in it when I got it.I've taken a 84 berli apart and that thing had mor wires and junk behind the dash than i'd ever seen.I'm not sure what all a simple LG4 has on them in the way of sensers and senders.The berli has alot of stuff that other cars of this year didnt have.is there a list or picture with the parts listed somewhere?
