LR4 firewall access for a cable

[Rubber Cow]

Necro Thread- looking for firewall pass-throughs for an LR4 and came across this thread. Odd- I've never had an issue running my Valentine behind an LR3 heated windshield. That said, most west coast PD and Highway /State Patrols use LASER. In fact, I can't remember when I was painted with a LEO RADAR in CA, OR, ID, WA or CO. Waze has done a lot for pre-detection.
