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?

Just to clear up the original question, yes that is the same wire that I intercepted for the ac relay. When I did my modification, I used some nice insulated bullet connectors so that I could easily reconnect the factory wiring if needed.

So you're getting an input signal from AC1, but your output is simply going to ground? This will idle the engine up since MS has an input that tells it the AC wants to turn on, but it doesn't sound like it will allow MS to delay the AC compressor from turning on. What you want is for MS to get a signal that requests the AC to come on, idle the engine up and then turn the AC compressor on after about 700ms. This will create a smooth transition as the AC cycles on and off. Right now it sounds like your idle up and compressor are turning on at the same exact time.

You are 100% right that the DIYPNP is a bit limited on outputs, especially when using sequential injection. You can however use WLED and ALED if they are not being used for anything important. On my setup I have ALED setup to simply turn on the CEL light when the key in ON but engine is not running. I could use that output for boost control if I wanted to.

I thought the WLED and ALED pins could only be used for on/off type of functions. If that is the case can I use them for the AC idle up and save the PAO for boost control? Will I need to run the WLED or ALED through a relay circuit? In the drawing from my previous post, I circled part of it, was that the correct AC relay wire you tapped into? Again, thanks so much for the help! I am not sure how I would have gotten this DIYPNP to work without your advice.
