ECU Pinout Values
Also, keep in mind. They way Toyota drew up the diagrams...the images below show the plug wires backwards from how they plug into the ECU. Like, if you were to unplug it and look at the plug head on. Just match/count the knotches in the connectors when you're wiring up to make sure you don't have it backwards.

Due to popular demand...I'm making some ECU pinout charts.
This should be helpful for those of you installing SAFC's and it even includes all the pinouts needed if you're planning to put in a standalone ECU. I double checked all the values and they SHOULD be correct. Just don't blame me if the ECU lets out some smoke lol.
Just be patitent and I'll release more as I have time. These take about 1-2hr each to make lol. So far I've completed the GS300 98-00 and 01-05. I'll do the GS400/430 eventually lol.

Hi JeffTsai. I'm new here.
Just wanted to ask. Are all the pinouts in your 99 gs300 diagram for a stand alone system.
I'm in the middle of a 2jzge vvti conversion from a gs300 to a 1973 toyota crown ms65
The pin outs are for any system. This just shows what each wire going into the factory ECU does/connects to which you need to know if you are rewiring for a standalone. Also he is almost certainly not going to respond. He hasn't been on the forum in a long time
