Default HELP! I need the ECU pin-out sheets for my '00 GS400!

I want a company to custom fabricate a Plug N Play harness to connect from my factory harness to my new Apexi Neo. However, they said they don't make one for my car but they would be glad to if I can provide them with the "pin-out" sheets. They said these charts are contained in the Lexus Service Manuals but I do not have that. Can someone please help. I need them to make me this harness. These sheets pretty much show where the MAF wires and all the others go. Please help guys...

I don't have a FSM but let us know if you get them to make you one. Did they give you a price yet?

FSM??? I think they mentioned around $275 for just the harness but I like things clean and neat, so I will pay the extra dough...

Back to some great CL member finding these sheets/charts for me! Please help or at least direct me to where I can find one...

Sorry, Factory Service Manual. $275 is the price of the Neo isn't it?!

Give me some time and I'll make an ECU pinout diagram for the GS400.

Hey Jeff, great ECU pin out diagrams. Can you do one for the 01-05 GS430 when you get a chance? I have have one w/ a few pin outs, (MAS,Ignitions,RPM,TPS and 12vt.) but not as large and detailed as yours

Jeff,

Thank you very much buddy!!! That is very helpful. I also went to my local public library and was able to find the pin-out schematic for my car; official from Toyota/Lexus Motor Corp. Nevertheless thanks for the help. I will scan and post up the documents that I got from the library on Monday to help out other CL members in the future.

Attached is the official pin-out diagrams from my local library for the '98-'00 Lexus GS400.

Hey Gillexus, I will run back to the library when I get a chance and post up the pin-out diagrams for your ride...

Rock-a-Lex thanks, I have most of the pin out locations. I really like the large and colorful diagram that JeffTsai put togather.
