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?

It really sucks that so much of the factory functionality goes through the ECU. Functions like the back up light, A/C, headlights, defogger, and Cruise Control are all pinouts in the ECU. I think once I get the car running I will figure out how to run 12V power to them. I will also need to determine what are sensors for CEL and what actually control something on the car. This is going to take some time.

You don't actually need to wire the majority of those to the ecu. Just stick with the basics of fuel and spark to get the engine running.
Stuff like the defogger input is just there to make the factory ecu idle up when there is an electrical load placed on it. The DIYPNP just monitors its own voltage and allows you to tune for that stuff without an extra input.

As far as AC, I didn't need to fully wire to the ecu to get it to work. All I did was supply an input signal so that the diypnp would know to initial AC idle up... but I would still wait to set that up once you have the car running.
