I used 1/2" split loom, which is actually too small for 5 16ga wires. But it's on & taped up with real wiring harness tape (not electrical tape), so it should be fine. It's zip-tied to the A/C hard line to keep it away from the pullies.

Cover the intake ports on the heads so nothing can fall inside. I was lucky.
