my car has the emssions removed and the vac lines that come from the top of the OMP injectors for vac, do i just plug the 4 to 1 to the UIM?

so your saying that your OMP injectors do not have lines on them? thats not a good thing unless you are premixing....for your sake i hope you are

The 4 injector vac lines plug into a spider. Splits 4 into 1. The the 1 goes to the small nipple on the firewall side of the UIM.

If you're gonna run premix (which I think is the way to go), then you just get a vacuum plug for the larger of the 3 nipples at the back of the UIM (facing the firewall).

If you're trying to hook back up the OMP and oil injectors any everything, then the vac. spider for the oil injection stuff connects to that same larger (of the 3) nipples at the back of the UIM.

If you are talking about the air bleeds for the oil injectors, they all join together and hook up between the throttle body and the AFM
