I am running a thin throttle body manifold with twin plenem chambers on my 355 can i run 2 ICV.s one on each throttle or onty one there is a balance tube that is on the back of the manifold to even it out The 4 wires to the icv one of them wood be a signal back to the ecu witch one and i dont think i can run the 2 wires back to the ecu only one

can only run one.ide fit 1 IAC in the balance pipe will then feed both plenums.i normally cut the iac boss off a TB and weld on pipes and run rubber hose or can weld it on
