Need wiring schematics for rear hatch

[GranPrix]

I need to figure out the function of a particular wire In the main harness that goes from the interior to the hatch.

The big black tube?
That is probably window washer hose

 

[GranPrix]

No not the hose

Which particular 'wire' are you pointing to? There are many there.... unless I'm too drunk and there's only one.

I think he’s looking for a pin-out of that harness.

Looks like some aftermarket stuff in there, or a wiring repair.

Try pages 299 and 300 for connectors

Yea I’m looking for the pin-out.

I saw those connectors on page 300 but that connector has more than 4 pins though.

I’m looking for the violet/white wire which I think it’s the Rear Gate Open signal..

page 299 is the 4 pin
pin 2 is violet / grey maybe confused with violet / white?
