Early +2 H/lamp Vac Pipes

Hi
Can any one confirm the route the headlamp vac pipes take from the switch on dash through the bulkhead . The parts book shows it passing through on the n/s bulkhead with a grommet , but when I stripped the motor the pipes ran through the same hole as heater pipes on the os. This would make sense as vac switch is in line with this hole .
I just want to confirm this before I refit heater , wirring loom , basically the whole interior .

I have a 71 Plus 2 S130 and my pipes run through the N/S bulkhead with one grommet per pipe.
