Installing oil temp and Pressure gauges???

[LaunchHard]

I have autometer electric oil temp and pressure gauges and i need some instructions!! Any help is appreciated.

Thank you.

did they both come with sending units?
if so
take out the oem oil press sending unit and put in the autometer one.
oil temp what kind of sensor did it come with?

Where is the oem pressure unit??

And the temp gauge came with a sending unit almost identical to a water temp sending unit.

Oil pressure is on the oil filter housing, you'll see it when you take a look.

I don't remember where I have my oil temp sender, but we can take a look at it.

on the filter housing unit, if its a 1g it has some stupid clip that slides on the end. Dunno if 2g's are set up the same.

Oooohhhhh, thats what that thing is!!!


Am i gonna need to mount the pressure sending unit off to the side, like the directions say, or is that unnecessary??

Mine is mounted on the bottom of my filter housing, just find where the stock 1/8" or 1/4" NPT hole is (can't remember the exact size) and replace it, they should be the same size.

Are the threads on the oil temp sensor the same size, or bigger (like ECU water temp sensor size)?

So I wanna run my gauge lights to either the fog light switch (don't have fog lights) or the dimmer switch. Which is better?? And which wires would i tap into for each switch??

Can i run 3 gauges and 3 gauge lights to one ground??

[Kevin 1G Drummer]

I would say run them into the fog light swich since there's nothing on that circut. You'll be just fine running all your gauges to a single ground. Just take a volt meter to the plug that goes into the swich and see which one is power, then run them off that wire.

DSM's use BSPT (British Standard Pipe Thread) for the oil sending unit
Aftermarket ones are NPT (National Pipe Thread)

The difference is one thread per inch (or something)

Long story short, i cracked my oil filter housing because of the thread mismatch. I had to get it welded.

Granted I was installing it in the winter, so the aluminum housing was easily cracked.

And if I just used more teflon tape, and didnt screw it in very far it probably wouldnt have cracked.
