I want to swap a 1990 SBEC setup into my 89 shadow. I have a 1988 service manual I believe should work on the car end, my old Pbody was a 88 with a 89 harness plugged in without any modifications.
but I need the 1990 diagram. the 1990 harness is a bit different. the 3 pin plug seems to have grown to 10 pins.
here are the 1988 diagrams, Im confident they'll work for 89 cars.
