If you haven't figured a way already, you might try what I did. I have a Saturn Vue, which is just like the Equinox. I ran my breakaway wiring alongside the hood latch release cable, from the inside firewall, into the engine compartment. I hooked the wiring to a straightened, wire clothes hanger and pushed/pulled it thru. Hope this helps.
