Hey looks like we did the same thing , I just used the Gromet to the left of the one you used. Both seem to work well.

Me, too. I was installing a remote starter and needed to run a 2-conductor wire to the engine, for a Tach signal and a hood interlock pin switch, and that was the grommet I used, too. Under the hood, I wrapped the new wire in the same black plastic loom as the existing wiring harnesses so it blended right in.
