im swapping an auto car to manual.the car im putting this into is a 89' turbo,and the car im pulling it from is a 87' turbo. and im swapping the entire engine and tranny from one to the other. will the plugs behind the dash plug into the pre 89' wiring harness? if not what is the easier way to do it rather than swapping over the entire dash harness with it? need to know asap,as im pullin the engine out,and dropping the other in tomorow. tyia
