Question about cutting the single wire, according to the installation instruction say to cut 1 wire only. The ECU wiring diagram show 5 wires need to be solder from the swift racing wiring harness, but the swift wiring harness has 6 wires ? Where is the last wire connect to (sensor 1 input orange) ? Is that the wire that u cut ? I am little confuse on that

 

Post A Pic Of It...then Someone Maybe Be Able To Help You Out.

 

When you cut that wire, you solder one wire to one cut end and then solder another wire to the other cut end

 

well put......... well put

 

I am looking directly at the wiring diagram. There are 6 wires from the swift ECU. You need to connect 4 of those wires directly to wires in your engine ECU. The last 2 wires(sensor 1 output and sensor 1 input) connect to the wire that you have to cut. You will cut Sensor 1 wire in half that goes from your engine ECU to your engine. You will connect SRT Sensor 1 Output to the cut end of your engine ECU sensor 1 wire that will be hanging from your Engine ECU. You connect the SRT Sensor 1 Input wire to the sensor 1 wire that will be hanging from your engine harness. Do you have the wiring diagram?

 

TexasGS, I'm not sure how different they are (other than to know they are two different products sold by SRT), but the original poster has a GS400 and you're probably looking at a GS430 diagram.

 

Yes, I am looking at a GS430 diagram but I think they are basically the same. The wire colors are the only thing that is different....I think . The quantity of wires and how they are wired is the same. Heck the wire colors on my diagram did not even match with my car. I think he was just confused with the Sensor 1 wire that needed to be cut. That is typical for all SRT ECU's.

 

thank you guys for the help , i will try continue working on it when i get a chance Hey Texas GS my diagram shows 5 wires from the SRT wiring harness connects to the ECU not 4 like u said.
Maybe 430 and 400 is a little diff ? My question was i wasnt sure where the last wire (Sensor 1
input orange) connects to ?

 

If I remember right the wire you cut is ground, if you wish to remove the intake/ecu later you have to reconnect it.

 

The 430 version has a total of 6 wires so maybe the 400 is way different as DaveGS4 mentioned. Maybe I should have stayed out of this . On the 430 you cut Sensor 1 and connect 2 of the 6 wires to each end of the cut Sensor 1 wire. The other 4 wires tap into the ECU wiring. I guess someone with a 400 wiring diagram needs to pipe in here.

 

Thank you guys for trying to help, anyone with a GS400 and has done the SRt intake please input ya option i will sure appreciated

 

I just used the pdf from the srt site. Worked just fine for me.

 

I think this should help. The GS400 wiring is the same as the GS430 except for the ECU location. The red numbers are the 6 wires coming from SRT ECU and the Blue numbers are the 5 wires going to the Car ECU.
As you notice wire 3 and 4 from the the SRT ECU connects to wire 3 ( ONE WIRE)to the engine.

 

Thank you all for ya input i got it now
