Vans drawings calls for a 5/8 hole in the firewall through which the electical wiring will pass. That seems a little small to me. I am putting together a list of the wires that will need to pass through my firewall in order to determine the propery size of the hole.
So far I have:
Starter/battery cable...2awg
cht x 4
egt x 4
tach
alt field
alt output
alt warning
manifold pressure
emag
pmag
fuel flow transducer
oil pressure
oil temp
hobbs
Am I missing anything? For those of you with similar setups, what size hole did you need? Any other advice about the size or positon of the holes would be appreciated.
