95pcm in a 96 car

Hey guys I'm working on swapping my 95formula drivetrain to a 96t/a. I wondering can I jut plug my PCM in and go or does anything need changed so I can still use the Aldl cable I have. The cable is for the obd 1.5. The obd2 plug but obd1 protocol?

96 harness will plug into the 95 PCM. Just make sure the tan data wire is on the correct pin in the 96 16-pin ALDL connector. I would also disconnect any ALDL connector wires that are not used by the 95 setup.

This diagram shows both ALDL connector pinouts:

The harness connector tables in this link show the difference between the 95 and 96 in red. As I mentioned in the other post, it's just the rear O2 sensors, the EVAP purge vacuum switch, the CKP sensor, and in this case the serial data wire.

Thanks man!! That's what I was looking for!

So basically if the tan wire is anywhere besides pin #9 move it to the #9? Then the other wires that are in red on the second link just cut them and dead them off? Well it's only one.

The both show the tan data wire on pin #9.

The knock sensor is different too, but if your using the 95 drivetrain then you should already have the correct sensor on the engine.

or if u use an lt4 knock module the conputer wont care about the dif resist in the knock sensors.

OP will be using 95 engine,trans, harness, and pcm. Only difference is 96 body and cabin harness under dash.

Not correct. 93-95 need a 4,000 ohm unit, 96/97 need the 100,000 ohm sensor. Mismatching the sensor with the PCM will set a code for the knock sensor, and the PCM will start pulling significant amounts of ignition timing based on engine operating conditions. You can alter the PCM internally to compensate for the mismatch, but not by using the LT4KM.

@Injuneer I notice that in the enter console of the 96 the plug is there for my trans perform button. Can I just plug it in and it works ? Or is there something that needs done? All the pins on the back of the actual switch have mates in the wires. Also I am gonna be using the 95s PCM so it worked in that car.
