So I was told my car was swapped with a 99 S52 with OBD1 intake, but still OBD2. I know the intake is OBD1 style. My question. How to tell if it is actually running OBD1 or 2?

you may not have an OBD2 port, but an OBD1 to OBD2 adapter works

You mean the round diag port? You can actually just jump a couple wires and skip the adapter.

Can you elaborate? I have always used an adapter since my scanner has OBD2 plug, so I have an adapter to plug into the round OBD1 port to read my codes. Curious what you're doing

The scanners only need to see power, ground and k(l)-lines. Those adapters just jump those corresponding wires.
Basically, I have a home made version of this: https://www.teewigo.com/ping-obd2-di...18-obd-break33
This not only allows me to scan swapped cars that never had an OBD port installed, I can bench flash ECU's as well.
