Can anyone hook me up with this. I had one and lost it. I don't know if the sc430 wiring diagram is the same. I tried matching them up and the only difference was where the light green cable was. on the sc 430 one is on the last connector and on the one that I had it said that it was on the 3 connector. Can anyone help me if you have the pdf file. . Also is there anyone in the 818 area that could help me out. I think my piggy back ecu is fried but don't know yet. Thanks

 

Are you in a big rush? I have the manual and could make you a copy and mail it on Monday. PM a mailing address. Otherwise I hope this scanned image helps.

 

Here you go. I asked SRT to send me these in PDF some time ago for GS400, GS430, IS300. Courtesy Mo at SRT.

 

Is it blue and yellow or black and yellow. Also I get it to start but get the CEL and vsc and vsc off light. Could I have a bad ecu???

 

The color is not that important, the pin location/position is what matters. My wires are different than diagram. my sensor 1 is blk/yel and sensor 2 is yel/blk.

 

This is correct, my wires in the factory ECU were different from the diagram. Use the pin locations and all will be well. Make sure you do this with the battery disconnected and solder all connections. Instructions claim this is critical for the installation to be successful.

 

did all of that but still get all the lights and bogs out at 3000 rpms. I am thinking that the piggy back ecu is bad.

 

As long as you are positive the connections are correct, MAF sensor installed correctly and all piping connections are tight, I would have to agree that the ECU is bad. Time to contact SRT.

 

Did you buy your SRT new or used? Are you running it w/ stock air box on. Make sure sensor 1 from the engine ECU is the only wire cut.
SRT ECU sensor 1 (MAF) green wire is going to the ECU and orange wire is going to the engine.

Reset the ECU-Disconect the batery for about 10-15 minutes, If all else fails and you can't get anybody to test w/ theirs, sent it to SRT and have them test it.
