As per the thread title - I need to run a cable from the engine compartment back to the area inside near the glovebox/centre console.

Has anyone done this or have any ideas of an easy route in?

TIA

 

Yes. In fact I've done this on lots of cars for various reasons. You just need to find where the wiring loom already passes through the bulkhead and put the wire through the grommet. Have a look at the instructions for installing a Real Gauge with the oil pressure option, as that requires an additional wire from the engine bay to the cabin: RealGauge Installation - TheJagWrangler

 

Thanks for that - that was exactly what I was looking for. I got a bit distracted yesterday looking into this, as I spotted a small oil leak from the transmission pan, so fixing that is now ahead on the list of things to do.
