Building a diypnp, Standalone harness wiring Options

[HardHead93]

I have been having nothing but trouble with my AEM FIC on my 5sfte set up. I have a 97 Celica GT Convertible with a newly rebuilt engine and a 16G CT-26 turbo set up. The ECU is not working well with the signals the piggyback is feeding the stock ECU. Based on a couple of posts I have seen on 6gc.net, I broke down and bought a diypnp 76 pin standalone. The diypnp has all the features I am looking for and the price doesn't break the bank. I just finished soldering the main board and am about to start doing the harness jumpers. Can anyone provide and example for wiring the diypnp?

Glad you were able to get the unit working!

Here is what I did for AC idle up.
I disconnected all AC1, ACT, ATS connections. With nothing hooked up to the ecu, the ac compressor would come on just fine.
Next, I looked at the vehicle wiring diagram to determine the wire that ground switches the ac compressor relay in the passengers side fuse box.
I cut that wire and ran the ground signal into the Flex pin. Then I connected the PA0 output to control the ac relay.

I believe the in order to use the PA0 output, you have to run it into the in port of relay1,relay2 or relay3 of the DIYPNP circuit board. Just double check this in the assembly documentation.

Does the car stall at idle or deceleration?

I am a little confused with this statement. Is the wire to cut the one that goes to the MGC pin on the AC amplifier or the one that goes to the AC magnetic clutch? Then when I cut the ground wire going to the AC relay in the fuse box under the hood. I connect the ground side of the cut wire to the flex pin on the DIYPNP. Then I connect the relay side of the cut wire to the PAO using one of the relays on the DIYPNP board. Set the PAO to output and the flex to input in TunerStudio under the AC idle up settings. Is that correct? Do I need to run the flex connection through one of the board relays?
