Yes..the OBDII System started in 1996, but the later 1995 models had provisions for the OBDII setups. Mine has a OBDII 16 Pin Connector, and was a OBDI LT1.
1995 and back still ran OBDI through that Port Connector, but the Wiring is inplace for OBDII System as well..I know cause I had to check and see when I was wiring in my 402 LSX.
On my car it was there...I'll look at my notes and tell you which ones you will need for OBDII..I believe it's 2,3,4,16 off the top of my head..but I will look for you and see.

1996 and up..yes.
ALL 1995 and back were OBDI Systems..regardless of the Connector.

Actually you have to run one wire from the Passenger kick panel to the ALDL connector to fully funtion the OBD II port ability. We have been doing this since 2001 I flip between OBD I and OBD II in my car
