B16A2: Does your ECM look like this ?

[TXCatalyst]

Need help! Bought the car used, should I have a connector A, assuming I have an entire 99-00 wiring harness and B16A2 from an 00 Civic Si ? (Yes, the entire car runs fine, no issues at all, just no a/c - which I troubleshooted to be that connector A is missing entirely!)

What is this RED connector - am I just missing some "splice" that goes from this red connector to connector A, perhaps ?

What about this brown connector that goes to nothing ?

How can I read what type of ECM I really do have from this picture?

You have a pt2 99-00 Civic Si obd2b ecu. (Notice the middle says P2T?)

Got it, thanks! Now, should I have a connector A at all ? I mean, I am completely missing it, yet the car runs fine.

get an obd1 to obd2b conversion harness taht way your stock wiring fits in your 99 si ecu,prices 75 and 150 for the harness,or get a 28 ecu(d6z6 sohc vtec and chipped)
