i converted from OBDII to OBDI how would i install the scanmaster?
same as obdI

 

All you need to do is make sure you attach the white ScanMaster wire to the tan data wire that goes to the ALDL connector.

you want the black wire at #4, white at #9, red at #16

i found the easiest and cleanest install is far as hooking up the scanner is buying an OBD2 molded connector and wiring up the scanmaster to it so it can be unplugged if needed. like this. got mine from www.akmcables.com for around $10.
