I really appreciate you for the quick reply and I know this been repeated many times but where will be the rear dif cooler as there are only to output wires from the female plug going to EVAP

And If I bought GT500 harness do I need to buy Y one ?

I found the the plug number in the trunk under number C3806

I could be wrong about the dif cooler but I used a harness from a gt500 and it seems that the dif cooler wires were just spliced in the harness which I removed when I did my install.

What about the Y harness do I need to get it?

Yes but I got mine use from eBay so everything was already attached. The harness for the gt500 and the GT are different but the plug in the trunk and the one for the actuator match. Long story short it works

You are lucky

Just to sum up from what I understand

GT500 harness will be connected to the plug in the trunk and the Y harness and EVAP will be connected to the GT500 harness and from the Y harness I will be able to connect it to the actuators with no any modifications with wires as that my big concern
Right ?

That is pretty much what I did. Although my car is 2022. I did have to turn on the active exhaust feature in the PCM. My car pretty much had the fuse needed and everything else. Never asked what year your car was but after I turn the feature on everything was plug and play.

Just saw this on eBay. It’s actually for the GT so that might be a better choice. Come with everything you need. https://www.ebay.com/itm/1566927915...hu7bQupSm-&var=&widget_ver=artemis&media=COPY

I have this plug in my trunk and I think wouldn’t work as my plug has 8 pins and this one is 12

Look behind the plastic in the trunk I think the plug is behind there. I’m at work so I can’t check my car right now but I will check when I get home.

Hi,

from the Hptuners I opened multiple files for car originally comes with AE and found that the AE1,AE2 and Idel switch are Enabled.

In this thread I have seen people have change only AE1 and AE2 and it worked with them

can someone confirm is it necessary to enable Idle Switch and what basically does this do if it was enabled?

Both mine were off, I had to turn them both on in my car.
