Thread: How to get fuel sender level to be seen by obdII

I have the ultra guage and in it for calculating the dte it would normally use the fuel sensor level but my vehicle doesn't support that in the obdII it says. So how do I get it to recognize it or do I have to wire it to certain pins in. The PCM?

EDIT: I see that blue connector pin 3 is "fuel level output control circuit" and connector clear pin 69 is "fuel level sensor input"
