Omni 4 bar map boost reference

[TalonCBR]

Hello all! I'm installing a omni 4 bar map, the current map on there has a small hose running off it T'd to the intake manifold and the fuel rail, which I suppose is the boost reference. My question is how to I hook that line up to my omni. The current map has a small nipple the line goes on but my omni doesnt have that, so do I have to get that nipple or run a hose big enough to fit around the hole the omni has? (Search didnt turn anything up) On my phone atm so I cant upload pics, but ill upload if someone requests it. I appreciate any advice you guys can offer! Thanks!

The omni map sensor has a tube built onto the body of the sensor. are you sure it's an omni map sensor?

I'm not sure if its a tube but there is a hole there, its just the hose on the old map that goes to the manifold is so much smaller.
