How to get fuel sender level to be seen by obdII

[tweeder]

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"

What are the ohms on the sending unit fro e-f? The fiero sender is 0-90 ohms. Seems like that's a problem I'm trying to tackle.

What parts are you asking about? Clearly you know the Fiero spec.

Well the fiero is obdI and the swapped PCM is obdII. I'm thinking that ohms are ohms regardless of obd. I'm looking at hptuners and it allows for tank size as well as fuel sender ohms, I was thinking of putting in the fiero values and tank size and running a wire from the fuel sender to pin 69, which in turn would allow the obdII to transmit the tank level through my ultra guage.

And again.. your post is not specific, meaning you aren't telling us what years pcm and fiero etc. So it's going to be kinda tough to help you. Even though I have all the GM manuals and could tell you any piece of info you needed... If...by GOD you would be a little more specific.

Lol sorry, it's an 86 fiero with a 2002 regal motor and a 00 Grand Prix tune over the regal PCM. Anything else?
