https://www.scionlife.com/forums/vie...603386#1603386


please people remember no one here on scion life or meself are responsable for any screw ups u make please be careful work slowly and cleanly. u will be fine


remove the grill





remove 5 10mm bolts






locate the oil pressure switch circled in green


unplug the sensor


remove the oil pressure switch i used a 15/16th deep socket i belive



remove the heater hose



water hose bottom remove


parts u will need




do not put the sensors together yet ths is what the oil sensor should u like



where to cut the water hose



eyelit on the water temp sensor because u will need to ground the sender so the signal wire will read acuretly


what the water hose should look like u will need to modify the hose adapter so that the bottom of the sensor is in the water path as u can see i had to cut the top nipple off and the sensor was turn into the fitting the sizes are very close so put some apoxy on the treds then thread the sensor into the hose adapter dont forget to put a new hose clamp on all the ends that u made by cutting the hose




assember the oil pressure sesnsor on the block please be carful the adapter will feel like it wont thread in but it will go in but please people be carful i am not responsable if u messup the side of your block make sure that tha after market sender is pointing twards the transmisson if u have a hard tome putting the oil sensors on the block dont be afraid to take the intake manifold off to get room to work with thats how i was able to get such a clear picutre to show u here



where the wire should be comming from dont forget to put the water hoses back on and titen all the clamps securly but dont over tight the green wire is for the water temp the orange for the oil pressure and the white goes to the white wire with the blue strip in the o2 sesnor and conescts to your a/r gauge


test the gauge and make sure its working right


wire it up where ever u have chosen to place your gauges and your done now sit back and enjoy the hard work u just went though

Very nice write up! I appreciate you taking the time to share this. It will really be helpful for me in the near future.

It looks like you recessed the guages. Did you actually cut the holes in the dash for the guages or are they surface mounted and just that slim? Thanks again!

 

holy daylong project batman.

Nice job -

- Saylor

 

thats looking good there man

 

so whats the fitting size adapters did use for your oil switches???

and did you also replace your intake manifold gasket too???

 

same on the tc?

 

Looks awesome!!!

 

havnt worked on a TC yet i do all my own work and learned alot from my mustang the key is to have a good parts store u trust because they will help u with the fittings

 

the adapter came from napa i took my oil pressure sensor to them and they matched the threads no i didnt change the intake gasket its a rubber o-ring desing and i still have low milage like 4k so i aplited gasket selant to the ports and retitened it i was told be my parts guy that with the low milage that gasket hasnt "worn" in so this may be a problen if u have high milage

 

if u falloow the steps i showed i would only take like 3 hours max but because i had to stop and take pic's of everything it took me 2 days to finish up any one has any more questions i would love to help as i feel our box's need better gauges

 

tag and bump :D

 

I didn't think four guages would fit there...Nice write-up

 

Great write up. You say that the aftermarket sender should be pointed toward the transmission. But in the photo it looks like the aftermarket sender is pointed away from the tranny. I'm using a VDO Vision Oil Pressure and Oil Temp Gauges. VDO makes a combo Oil Pressure Sender and Idiot light switch in one unit. Do you think that I can use this combo unit and replace the stock xB oil pressure switch? That way I won't have to use a "T" fitting. Or I could use a "T" and put the Oil Temperature sender on the other side. Does any one know what the small Acute triangle and the number 20 means on the stock oil pressure switch? Do you think that's the "turn on" low pressure?

 

nice write up!
