Are you using the stock drivetrain currently?

I just did this same swap about a month ago, everything is pretty straight forward except for a couple exceptions.  The major pain points were the brake/clutch peddles which need to be swapped and the clutch cylinder has to be moved from the manual car to the auto. The 85-88 body harness puts the starter wire on a different pin for auto and manual cars and on some 85 harnesses the trunk release is run through the engine harness. 86+ does not run the trunk release wiring over the engine harness.  Also, you'll obviously need to swap the shifters, other than that it's a basic engine swap.

Read this forum post for more info on the wiring:

Let me know if you have any questions, like I said I just did one so I can probably help.

Yes I'm using the stick drivetrain . V6 other then the shifter and peddles ect.. Will I need to swap the whole engine?

You'll have to drop the engine and cradle to get at the transaxle but you'll be able to just swap the transaxle and keep your engine.  That being considered, you won't have to change the starter wire as you'll still be using the engine wiring harness from the manual car.

No engine swap. You will have to change the pedals to brake only, change the console shifter, change the wiring loom, change the shifter cable, change the trans and axles, plus etc.  This is NOT an easy swap.
