Does anyone have the ECU pinout? A complete pinout with what every pin is for. This is for an E-manage ultimate on a 05 GS. I have been searching for the past few day and have come up with nothing. If you have one please post it up or PM me.

Thanks!

Eh, anyone? It seems as if my only option is to buy the $150 service manuals at this point. Looks like this information is not available anywhere!

Jeff,

I did a search on the GS forum for "ECU PIN" and this popped up right away... what you're looking for?

I need the complete list of what each pin is for. I'm hooking up a Greddy Emanage Ultimate so it needs the injector, ignition, and some sensor wires. Do all 2nd gen GS have the same ecu pinout regardless of year or gs3/4/430?

I have found a complete pinout for a JDM Aristo v300....the connector is the same but I think the pins are in different locations.

I suspect they're similar but slightly different, but only guessing this because I know SRT sells different ECUs (for example) for 400 / 430.

Hey thanks Dave but those diagrams only give about 1/4 of the info i need. The SRT intake one you just linked only gives pinouts for 8 wires. I need it for around 35 or so. I will try at the dealer to see if they can make me a copy. If not then I guess i might have to buy the service manual.

By chance do you, or anyone else have this for the GS400. I am looking at the same thing you are except I am putting it on the GS400.

Thanks in advance,

Pete, this is the diagnostics? Is there another page that tells what each pin corresponds to? Something like where the RPM signal, MAF signal, TPS, Injectors, Ignition....etc.

Thanks in advance!

Edit: Ahh, I was reading the chart wrong heh..... I think this chart pretty much covers it! Thanks a million Pete!!!

Now I think I'm going to stay up the whole night figuring out the wires! lol

Hey Pete,

Is there another page somewhere in the book? This page has about 3/4 of the wires I need. However, I'm not seeing the water temp, MAF, Throttle, and a few other sensors on this page. If you dont see them then its ok, just tell me. If you cant find it then I will be making a trip to the lexus dealer tomorrow to see if they will copy me a page out of their service books. If worse comes to worst, my friend's friend's bro is a master tech at sewell lexus. Hopefully he will be able to help out.

Thanks in advance!!
