Ok I was reading another thread in the forum, talking about the A9l and A9p which is better issue. And it was mentioned that the corresponding computer should be installed depending on trans application and if the car has been swapped or not. Now my 93 lx was factory AOD. When I purchased it, it had been swapped to a T-5. Recently my computer took a dump and I had to replace it, I had an A3m, I replaced it with an A9l. So my question now is, do I need to repin anything? Or check to see if it was done already? If the car was a factory AOD, there will be some differences in the harness, correct? Thanks for all your help and wisdom guys.

The difference is in the NSS circuit and the O2 harness.

Pin 30 on your originally AOD car might have been cut if you have an A9L or other manual trans EEC.

If it wasn't cut, do I need to cut it? Any other mods that need to be done with the a9l?

It'd be time to check further to see if the harness was swapped already. The difference is in how the the circuit is grounded.

Unplug the EEC and remove the coil wire on the dizzy. Crank the engine over while checking for voltage on pin 46. If you have voltage, you need to repin the o2 harness.

Thanks for all the information. Let me know if you find out which pin to check for voltage, so I can be sure the swap was done correctly. Thanks again for all of your help guys.
