Installing Apexi El2 Gauges, Where To Put Senders?

[GTRKING33]

Hey guys,

Have bought a 33 gtr

Car has three gauges mounted

1x boost gauge

1x oil temp

1x oil pressure

brand apexi EL2

the previous owner passed the sender units to the engine bay but didnt install them.

there are 4 attachments each 1 is pictured, also pictured is my engine bay

Can you please advise where to put each fitting to get the gauges to work.

Thank you in advance for any replies or help

You need a sandwich plate (between the block and the oil filter) to provide a spot to install the oil temp and pressure senders.

The boost guage's sender needs to be teed into one of the vacuum lines at the rear of the plenum. The one that runs to the car's original boost sensor is the best choice.

GTSBoy, thanks heaps for the help

What sandwich plate do i need? an apexi one or any generic sandwich plate will have space for those sensors?

Does anyone have any picture circling which vacuum line should be teed into?

Whats the thing in picture 2?

Any old sandwich plate will do, provided it looks decent. Brand whores need not apply.

The factory boost sensor is pretty easy to find. It's up on the firewall near the brake booster. It has one small bore vacuum hose and a wiring loom plug.

Do you have any pictures of what i should be looking for? I still want the factory boost gauge to work as i think it will look stupid if it doesnt move

Just to confirm about any oil sandwich plate would this one on ebay for under 30$ be a straight fit. eg unscrew oilfilter and put this in, then connect both of my sensor into it? all of the sender units have a generic size?

No I don't have pictures. I thought my description was pretty clear. Go and look for it yourself. And I did say to Tee it into the hose, not just cut the factory sensor out of the loop altogether.

Most oil sensors share the 1/8" thread.
