just a guess i would say you would need a 97 bcm, ecm and harness.

 

There are differences in the wiring harnesses, particularly the interfaces to the dash. Shoebox has all the connector pinouts on his website. Studying them will help identify the differences.

To be able to scan with an OBD-II scanner, you need to swap your 12-pin ALDL connector out for the 16-pin OBD-II connector, then make sure you connect the correct wires from the 97 LT1 PCM to the correct pins.

 

any idea how i would do that or what colors to match up?

 

You need the wiring diagram for the 97 ALDL connector. My Chiltons has a 96/97 diagram that show that the PCM has 3 wires that connect to the ALDL connector:

Conn #4/pin 7 (does not indicate purpose) - purple
Conn #4/pin 20 (output/field service enable) - white/black
Conn #4/pin 30 (serial data) - tan

You should check that with another source, because Chilton's isn't always reliable (Shoebox has 96/97 connector pinouts on his website).

As far as which pins in the ALDL connector serve which purposes:

Pin 2 = serial data
Pin 4 = ground
Pin 5 = ground
Pin 6 = output/field service enable
Pin 9 = serial data
Pin 16 = Battery voltage

Connector pins are arranged:

1 - 2 - 3 - 4 - 5 - 6 - 7 - 8
9-10-11-12-13-14-15-16

If I was doing a swap like this, I'd make sure I had a set of the factory (Helm) manuals for a 1997. The info I am giving you is off references I have, but there is no substitute for the factory info.

 

how hard would it be to put a 97 cluster in a 96...is it a straight swap or if not can it really be that hard?
