Thread: Engine oil pressure gauge connection

Fit a T to where the oil pressure switch is located, which is on the left side of the block near the back of the engine behind the spin-on oil filter.

Did you mean TD5?

I already have the ATF sensor organised and welded to the bottom of the ATF sump, but have no idea how this engine oil pressure gauge connects to a TD5.

Picture of the supplied engine oil pressure unit is attached, with a hole in the end and then cable, so obviously there is a sensor within the chrome bit and cable connection to the gauge.

So, showing my ignorance, how/where to fit it at the engine end?

Do you plan to keep the original warning in place? If so you will need some sort of dual fitting, like a 'T' piece.

The OP switch is just behind the oil filter cartridge.

My RAVE CD is hiding, so Haynes will have to do.

Just be aware that you will probably find 2 wires to the oil pressure sensor and think one has become disconnected.
In fact Land Rover got a deal on 2 wire looms and one wire is all that is required so the other is just sitting there doing nothing.

Nothing like having a spare..

Christian from LR Time installs an oil pressure sensor and gauge in their Disco 3 in this episode.

I hope it may be useful for you. At any rate they are great fun to watch.
best wishes.

Yes TD5 - fitted to RRC softdash, just to confuse the issue.

Just to make it more annoying the thread for the factory oil sensor can either be m10x1 or 1/8 npt. Iirc later engines are M10 but it's not uncommon for older engines to have the later oil cooler assembly with the M10 thread as well

And if you can, use a steel T piece, not brass.
Brass can fatigue (seen it first hand), break and leak/fail.
