[87Baron2.5]

I am trying to take a 1987 Lebaron turbo car and turn the wiring harness/computer system to 89. I have a 1989 Lebaron TII donor car. Just wondering what is entailed. Like how much wiring you can leave in(i.e. in the dash area)and plug and play. Do I leave original leads to fuel pump, etc.??? Any help would be great, hopefully someone has done exactly this...

what body Lebaron? Hbodies might have the 50 pin at the firewall where it would probably be plug and play. Jbodies are Daytona like which means you either have to replace everything or cut and splice the engine harness into the main harness.
