Wiring in Continental flex fuel sensor 13577394

[ChrisAudi80]

Have a Continental flex fuel sensor 13577394 on the way so just want to double check.

Will wire in as follows:
sensor VCC to sw 12v (I thought these sensors used 5v feed)
sensor GND to power GND
sensor signal to EC18-8 with modified ini file according to Jason's write up.

Correct?

BUMP.

To follow up on this:
I have a dedicated fuel pump relay in the trunk. The relay I use has a second switched 12v (pin87a) out.
Can I use this to power the sensor?
What ground can I use? Can I use the same GND as my FP?
