E36 Diagnostic port

[motorsports_3]

One of my friends with an OBD1 M52 is trying to read a code but the diagnostic port does not seem to have power. I am talking about the round one, that is on the e36 wire harness. I could swear that I had read here one time that it needs a power source. Does anyone have an idea on that.

He has the wire adapter from Gregslow if that makes a difference.

TIA

Thats true, ill tell him to do that.

Im still kinda curious about the port though. If they dont work, ill prob just remove mine to clean it up
