Apparently theres a deal where you run a 4an line into some sort of a small drum the size of a pressure regulator... the other side of that drum is filled with an inert liquid. If the line pops,l you get a small amount of whatever non hazmat liquid on you and thats about it... still lets you get a live analog reading.

As for the ecm grommet - theres so much running through there, im strongly considering drilling another smaller hole next to it to transfer a bunch of wiring... There is a grommet behind the windshield wiper mechanism that ill have a look at soon...
