No, I had a light bar but had it slaved to light functions available in the engine bay, so no need to deal with the firewall.

Hi,
I snuck a cable through the rubber boot for the clutch cable at the firewall. 
Used 20mm long about 8mm (old bit of pvc) hose, neat little cross cut, insert hose ,  insert wire, seal up around with silastic or similar, used bluetack to plug ends. If needed in future, pick out bluetack , pass wire & plug again .
Hope it helps.
PS- if yours is auto, could be a plate  where cable goes
