I bought a used SRT Intake and ECU. I installed thte intake and was not able to download the instructions from SRT's website. The piggy back module has 6 wires. Orange, White, Red, Black, Green and Purple. I have my glove box down because I was just installing a new CD Changer. I need to know where to connect these wires to. Does anyone have any info or a PDF on this?

 

I just sold my intake and ECU so I don't have the wiring instructions but thenew owner does. I can tell you that the ECU connects to a box under the hood on my G430, not in the glovebox. Someone with the wiring diagram will chime in to help I'm sure.

 

Eric,

Looks like from your profile that you have a 1999 GS400. If that's correct, this PDF should work. Right click and save as.

Thanks alot guys. I really appreciate it. Now all I need to do is go get my solder gun back from my friend who I loaned it to.

Thanks

 

Is the ECU on a 99 GS400 the same on a 99LS400. I know that mine isn't located in the same spot, but is it the same ECU?

 

The ECU is by the driver side light in the engine compartment. It is covered by a black plastic cover with 2 bolts.

 

Are you talking about a 99 GS400 or a 99 LS400?

Also, when you say solder, should I cut the wires, or am I going to be running a wire tap?

For the SRT piggyback ECU, only 1 wire is cut. The rest are just taps.

 

That is correct. You will only need to cut 1 wire and tap all the rest. They make a big thing about soldering. I soldered mine and have not had any wiring problems with connections. I recomend following ther advice. You need to do the ecu when you do the pipe because the car will run like crap. You still want to reset your ecu 1 in a while by disconecting the baterry or the ecu fuse.

 

Does anyone have a wireing PDF & how to install a Intake with ECU for the GS430?

 

yOU SHOULD BE ABLE TO GET IT FROM THERE SITE. IF YOU CAN'T FIND IT EMAIL THEM...i HAVE A 400...
