Hi

 

I just got my SPA dual digital water and oil gauge, and I need to find a good route through the firewall on the driver's side for the sensors and wiring. The oil pressure sensor plug is quite bulky, so the hole needs to be a descent size, maybe 3/4 " minimum. Any ideas? I already found a good place for the passenger side, but the loom isn't long enough to reach that way.

 

Oh, and I would rather not have to take the wing off to reach it too... ;-)

 

Thanks in advance!

Just go through the Bonnet release cable hole in the Drivers side footwell. No need to remove any trim, just poke through.

This info from the aussie 300zx forum may help.

Nice one, thanks! Do you think the bonnet release is big enough to get the plug through? Maybe 3/4" size?

Think it may be a squeeze - what's on the other end of the loom? You may need to cut the wires then reconnect after feeding them through..

It's a 90 degree elbow plug for the oil pressure sender. Very nice shrinkwrapped loom that I don't really want to cut. I may have to take the plug appart and poke the contacts through, then reassemble the plug on the other side. Alternatively, I had a look at the grommet on the website. If it comes out of the firewall like the one on the passenger side, I can remove the grommet, cut it and feed the sensor through the hole in the metal, then put the grommet back in around it...?

Take out your battery, there is a 2inch square hole filled by a rubber gromet. Then pull back the passenger side arch liner and you can then thread through to the car. The cable will come through near the ecu in the passenger footwell.
