Default Wiring 2007 egr pig tail onto my 2006

Ok i got the replacement tube/egr and it all installed with no issue until i realised the pug was different. I got the new pig tail and all the wires are white (which doesnt suprise me) I figured if i just go one by one i couldnt screw up wiring the new one. Apparently i was wrong because now unless my egr is unplugged my car will not start. Long story short i need a wiring diagram as to which white wire goes to what colored wire on my car. Thanks in advance.

Post #2 from this thread should be useful. If you got the kit that came with the new EGR tube, it should have also came with instructions for installing the new plug.

I saved 100$ and bought them seperatly so no instructions. That does help alot thanks. Is there any thread that states what white wire to what colored wire? like i said i thought i could just do first wire on old plug to the first white wire on the new and so on.... Clearly that didnt work because my car didnt start. I am mechanicly enclined but i am in no way a wiring expert. Im like a 3rd grader lol pictures help alot. thanks again.

The positions of the pins/wires in the plugs should be labeled with letters.

After looking at the TSB and a wiring diagram, I suspect that you got the two grey wires connected backwards since the order of the wires in the plug is exactly the same as your old EGR valve.

I have attached an excerpt of the wiring diagram for the EGR valve and the TSB for replacing the old EGR valve (Delphi w/vertical plug) with the part with the revised design (Siemens w/side plug). This should be all the info you'll need. If you still can't figure it out, you'll need to take the vehicle to a dealership. You will need to have the PCM reprogrammed by a Chevrolet dealership after you are completed anyways.

In a nutshell, the new EGR valve won't work properly because the PCM is currently calibrated to tell the old EGR valve what to do and when to do it. Because the new EGR valve is different than the old one, it may not work properly and the PCM will likely throw troublecodes.

Taken from the first page of the TSB I previously posted:

Important
This EGR valve kit is used to convert a Delphi EGR valve equipped LNJ engine used in the Chevrolet Equinox and Pontiac Torrent to a Siemens valve. This kit contains all necessary parts for conversion.The Powertrain Control Module (PCM) calibration must be updated for the Siemens EGR valve to work correctly. Failure to install an updated calibration when using this conversion kit may cause PCM diagnostic codes to set, resulting in a "Service Engine Soon" indicator lamp to illuminate.

I am also doing the same thing with my car, (equinox 2005) and I have noticed that there are two grey wires. I was stupid enough to cut the old connector and now I am left with two grey wires and I don't know how to tell the difference. not to mention the only real distinction in the other 3 cable is the orange one. I see there is a light brown cable and a purple looking one? I want to say the darker is the so called brown cable and the lighter one is the tan but what really got me confused is the two grey wires. any help would be great.
