Connect B pin 11

In the wiring diagrams I have found for B11 it shows as an empty pin. Is the ECU capable to send/recieve any type of signal on this pin? Trying to figure out some of the wiring in my car, everything else makes sense except this one pin.

More details please, what vehicle, what year?

It's a 1995 Accord LX, PND ECU with K Pro, the harness is Hasport's. This is the car they used to create the mounts for the Accord K swap. They tried putting A/C in the car prior to Hondata releasing the VTP as an alternate AC switch. Been trying to undo what they did with the a/c so i can wire it correctly (it never worked right), and in trying to do that I went to trace back all the wires from the ECU. B11 has a wire that goes under the dash on the drivers side of the car, it's the only wire that doesn't show up on any wiring diagram I have found. So i'm figuring that's my best bet to as how they sent the signal to the ACS.

Is B11 used for anything on the TSX or 05 Type S harness?

At this point you will need to contact Hasport.

It's been a hassle, even with being local, no one seems to remember how they did the A/C, as it was second to getting the actual swap done.

I'm just asking if any of the K series ECU's use B11 for anything. If the ECU is null at B11, then I can go from there.

Actually Mike, the A/C worked fine for months, until the compressor started having issues, and the pressure switch was replaced before you took posession of the car. You can rewire it if you want, use the 2002 RSX service manual and the 94-95 Accord service manual..

I was always under the impression that when it did work, it was for a short period of time. Didn't know it worked for months at a time. But, it killed a new compressor I just put in it, and i've got a 3rd about to go in, don't want it to do the same to this one, so I just want to verify the wiring.

Do you have any idea why there would be a wire going to B11?
