Well after everyone on the thread told me not to i did it anyway. Swapped in the 87 TII into the 89 GXL. As everyone said it was a job but wasnt that bad thanks to Fred at the Mazda dealer. I had to cut and resolder the dash harness to make it fit the 87 ECU that wasnt that bad. But when it came time to cut the FEM plugs that was a pain. Luckly I found a mazda dealer that let me borrow the wiring diagram for the 89 since no one on the internet seems to have it. Its turning out nice everything seems to work great. The engine is in the car and now i a bolting it in. I was however dissapointed when i went to mount the tranny in. I was told that it would bolt right up but it seems someone was wrong. I am going to have to make a bracket i suppose. My question to anyone that has read this far is: The car was an auto, as you know the bracket is farther back that the manual but i put the auto bracket on and the end of the tranny sits on it. Will this work. If it sits to low could i maybe ad some more busings to sit it up higher. Anyone that knows please let me know. I will maybe do a right up on this and how i did it since i dont think anyone has actually done a series + TII swap. Thanks for reading.
