Introduction:
I Have a 1997 Acura Integra GS-R swapped into my 1993 Honda Del Sol "S'. The engine is powered by a 1995 OBD1 GSR P72 ECU. I have recently come across a snag in completing my swap to perfection. My car started running horribly. My car started running rich and I've had to rev up to 3K RPM to get a decent accelaration out of my engine. That led me to doing a code check and i came up on a CODE 10 (Bad AIT sensor and/or circuit). So what I did was replace the sensor and that made the problem good for a while, then the car ran bad AGAIN... So I went to replacing the O2 and the AIT sensors which fixed the problem for about a week. Then my car ran like a it was a newborn baby on a thousand laxatives. This CODE 10 is such a hassle. I've been stuck with my car like this for about two months constantly asking automotive friends and going in and out of forums looking for answers. And so my final solution which should have been my first is to ask those of WWW.HONDASWAP.COM.
The Attempt to find a solution:
So I opened the hood on the very next oppurtunity to check on the AIT circuit since I've replaced the sensor multiple times already. I followed the wires back to the ECU. Note: Theres two wires from the AIT sensor are a BLK/YLLW converted to a thick green wire and a BLU/YLLW converted to a thick blue wire (seen below). I find the green wire going straight to D17 ECU connector pinout hole (INTAKE AIR BYPASS CNTRL. SOL. VALUE), and the blue wire is just hanging there. But the problem is theres a red and yellow wire already in the D15 pinout hole (Unable to track it down but looks like it goes down toward the Oil pan or Oil pressure sensor). Now I'm trying to figure out where I can put this blue wire which is supposed to be in D15 to properly set up the AIT circuit and send the right signal to the ECU so it can do its job and adjust? I was told I can tap/splice/Solder the wire to the D11(TPS) or either of the 2 Signal Ground wires (D21-D22) would this be correct information?

1)No MAP?! Is this ok for an Obd2 B18c1 swap into a 93 Obd1 EG? Could I plug in my AIT sensor to this pinout to set up the AIT circuit properly?
2)TO ME it looks like the Blue wire could have been crammed into the CPK pinout or is that JUST me? Could this be the solution to setting up my AIT circuit and clear the CODE 10? Can I plug in the AIT wire to the CPK pinout?
3)As you can see the blue wire I followed from the AIT sensor is just hanging there, and pinout D15 (AIT) is already taken by a red and yellow... and the small thin silver exposed wire that is soldered to the blue AIT wire runs to the A26 pinout (LG1-Logic Ground) Note: Unable to get a good clear picture. Any Ideas as to where I can plug/splice/solder this wire to complete the circuit and send the proper signal to the ECU?

I would like to thank any and all of those that can help give some information for a first time swap owner. Thank you for any and all your help!
