HELP! CEL on and code 1281

[rlddlr53]

My car was not wired correctly for the diagnostic port.

Why would any wiring need to be done for the diagnostic port?

I believe M3PO is referring to the data port (big round plug with a cap on it) that is built into your engine harness and not the OBD port you are probably referring to.

And what exactly did you correct? Thanks in advance!

If I remember correctly there was a wire to the e30 diagnostic port that was not wired correctly and spit the code out. I bought the car already swapped and my friend fixed it. I dont think he is into e30s anymore or on the forum. If I am not mistaken it was wire 22 or 23 and purple, im not sure
