I recently added the air pump simulator to my 97 TI with an S52 motor and it works great. I created a PCB layout for me and anyone else who would like to use it. I got all the parts from radio shack and etched the board. Pin 1 in the circuit below is the square pin on the board. If you do not feel like making a board I uploaded the board files to batchpcb so you can buy one pre made for fairly cheap. http://batchpcb.com/index.php/Products/53138

The PCB can also be used for the 4 cyl engines, just don't populate a relay and a potentiometer.

Here is the parts list that I used from Radio Shack:
1 - 7805 +5VDC Voltage Regulator (#276-1770 $1.59)
2 - 100K – ohm Micro Potentiometer (#271-284 $2.98)
2 - SPDT Mirco Relay 12VDC (#275-0241 $9.38)
1 - Project Box 3x2x1 (#270-1801 $2.49)
