hey, i just got my gauges and im in the dark about installing the oil pressure gauge, its the electrical gauge from autometer, and it included a sender thing thats the size of the actual gauge. from what i've collected, im supposed to get a t fitting and screw that into where the oil pressure switch is on the block and then then run the sender into the T and also the oil pressure switch to the T also? is this correct? i have also heard if i hook up the stuff directly to the block, it will eventuly break or fall off because of the vibrations, so i should run a loop to the fire wall and mount it there. now, what plumbing do i need to get? i don tknow anything about the hardware, i always see #'s like 4an and bsp or stuff like that. can anyone tell me some part #s of the hardware i need to get so i can hook the gauge up? also do i just simple find a spot on the fire wall and mount it? what would be a good way to mount the sender to the wall? im thinking of getting some c clamps like the ones domestics use to do their exhaust piping. and drill holes in the wall and bolt it down, i know that i would have to take off the dash but thats no bigge since i need to take it off anyway. also wheres a good ground where i can ground the gauge too? it says it needs to be on the engine, soo yeah. i think i know what im doin. but if people can supply me w. some part numbers to the peices i need to get so i dont go to the hardware store w/ my finger up my butt, thanks

 

what you need to know?

 

Here maybe this will help, this is described on a GSR block but should be pretty standard on all newer honda motors, first things first you don't need to drain the oil to remove the stock pressure sender, I didn't drain mine.

Here this first pic is of the T bracket they are all talking about but I opted for an elbow fitting and you will see why in the second picture:


Now here is a picture of the sender they are talking about:
(ignore the axle grease on the firewall I had a CV boot blow the day before this picture was taken)


Now as you can see I chose to run an elbow fitting out of the back of the block ran a SS braided line up to my fire wall to a T fitting then put the sender in the T and secured it to the firewall, when I get around to it I will put the stock sender in the other side of the T and extend the stock wiring up to the new location, I chose to do this because you can see how big that sensor is, and I have seen those senders because of their size and weight brake the T fitting off at the block and well then you blow all your oil and possibly the motor.

Does this help at all?

Oh yeah and by the way about the wiring ok for the light there is a black and white wire, pretty basic wiring here white is lights tap your fuse box for this, and black is ground.

For the three wires coming out of the gauge one goes to the sender, the other is ignition(when on or running) and the third is ground, now on the back of the guage where these wires go should be 3 threaded posts well next to each post is a label of what wire goes there, should be a little circle next to each post, one has a + another has a - and the third has a "S" I believe
+ ignition
- Ground
S sender

This was a reply to another post he had more questions just take what you need from it
