Are there any holes/grommets in the firewall I can use for running wires to the cabin in an EF other than the one above the ECU that comes out next to the strut tower? I already have my battery cable, OBD1 conversion wires, multipoint conversion wires, and wideband wires run through it so it's getting pretty cramped lol

 

Yes just look for you self I can think of 3 off the top of my head lol.

 

I already looked, that's why I'm asking lol

Mine has ac, cable speedo, and a cable tranny so all of those are out of the question haha

 

Hear are a few
Where the ac lines run threw

Where the fuel line run threw the fire wall

Behinde passenger side shock tower is a empty. Gromment. As you can see I have my window wiper motor wires and map sensor wires ran threw it. Did that when I did my wwire tuck
