Another "what's this hole for" question

[Bret Schneider]

Anyone know what these holes (in the red box) are for?
I relocated the battery and am thinking of routing the battery cable along the back side of that rail.

Thanks

Run a circuit breaker at the battery.

I believe the two inner holes for your rear defrost blower wiring or rear speakers. They used a clip and you lay the wire in it. Somewhere along there your rear seat has two hooks that hook into slotted holes. So if you’re going to run the stock seat back, check where those hooks go in too.

Another use for that section is power window wiring.

there is a trim panel that goes there i think the holes are for the clips
