Through the firewall!

Greetings,

I need to run a couple of 10-ga power leads, and a tranny temp sensor lead, through the firewall of my 2000 Expy.

I was hoping to make the hole somewhere around the removeable oval panel in the top of my dash, but it's just too tight under there.

So, experts: what's the best location for a wiring hole in the firewall?

Thanks a zillion!

Best regards,

In the F 150 and, I think, in the Expys, there's a rubber plug above the accelerator pedal and towards the passenger side. It is visible from the engine side below the power brake vacuum housing. That worked for me.

I had to drill a hole above and to the right of the gas pedal cable as it goes through the fire wall from the inside of the Expy.

Once my cable was in place I sealed the opening with RTV.

Don't drill to deep or you will hit the engine.

On my '97 there is a round, black rubber grommet in the firewall below, and a few inches toward the engine from the master brake cylinder. One factory cable already runs through it. Pop it out towards the engine compartment, put a slit in it large enough for all your cables, the push it back in. I dab of silicone will close up any tiny holes left. I have five power cbles running through that for my uses.
