Apexi NEO wiring diagram help please
I will be removing my srt ecu and replacing it with an Apexi neo, unfortunately I will be getting the neo w/out the manual so I need some help. I searched for the diagram on here and noticed there were some discrepancies on which diagram to use for the neo, will someone that has done the neo or knows exactly which diagram is correct please inform me. Thanks, Blake

Well, I bought a plug 'n' play harness for my "Neo-to-GS400" connectivity so I didn't have to solder into my ECU harness; so I can't help you with your install. I am positive I can find the paperwork that came with my Neo. I can scan it and e-mail it to you but you will have to wait until tomorrow...the manual is at home and I am aleady at work.

Thanks, now I just the wiring diagram. Once I install it at my house can I drive to the dyno place that is going to adjust it, or will it need to be tuned immediately?

jriggs - you beat me to it! lol
Bliggity - I left it disconnected for the drive to the dyno shop because a setup of the NEO is ESSENTIAL before you drive the car or you can damage the engine (as per the manual. When they were ready to tune it they simply connected it, set it up and started tuning. GL!

Visit there website: Boomslang.us. They are EXCELLENT at making custom PnP harnesses for ANY vehicle and for ANY application.
When I was ordering it I was a little weary because they had never made a custom harness for the GS400 with Apexi Neo connectivity. They needed my GS400's pin-out sheet (I obtained from my local library) and a copy of the Apexi Neo's installation manual. I then estimated how much length in feet that I needed; I think it was something like 6' (to play it safe, you can always ziptie the extra).
Less than one week later it was at my door and all is well. Plus, when I sell my car down the road at least I can put everything back to stock without hacked ECU wires.
They are great people to deal with...GL!

Do you have a GS430? The ECU pins are different. See if Boomslang will make you one for the GS430,see if they have done one before.
I had one made by Autosport it cost more I think $280 I could not find any one making one for the 01+ GS430 at the time. I sent Autosport pin locations from the service manual.
I believe the Neo has same connections as the S-AFCII- pwr,grd,knock1 &2,Maf,tps and rpm. The SRT GS430 ECU locations area a good start.
The only difference from SRT's & Apexi was the RPM location. SRT use the signal from the ignition and Apexi uses the signal going to the tachometer.
