What's this 18-pin connector for? (1 Viewer)

[gummycarbs]

I found this 18 pin connector (15 pins used) above the left, rear quarter panel, on top of the wheel well. Any idea what it's for? I've looked at the FSM electrical diagrams and I don't see it anywhere. Maybe it's for some non-US market feature...

Not used in the US market.

Any idea what it's used for in other markets, Dan? I'm wondering if I could repurpose it for something else.

I am not certain but it may have something to do with the sub fuel tank controller.

Very interesting, thanks!

You might look at your EWD and see what colors are common for grounds, ignition, battery, etc. Then confirm them with a meter.
Just a thought.

I found this thread that, as @cruiserdan said, shows that it's used to connect a fuel pump ECU module for the factory sub-tank:

@elmariachi went to the trouble of tracing the connections and documenting them. Good stuff.

It would be very interesting to get hold of a non-USA EWD and FSM, has anyone got a source?

There must be some given the differences in configurations and options.
