I am adding a mechanical oil pressure and temperature gauge to a 1991 Cherokee 4L Auto. Is there an existing hole in the firewall to pass the cables from the passenger to the engine compartment? If not, where is the best place to drill a hole in the firewall? Thanks, in advance.
How to get gauge cables through firewall?

Don't know your answer but the best method is to check for other pass-throughs. Brake, gas, etc. all have rubber grommets and usually there is enough room to thread another wire through.
