couple gague questions

[400exboy2]

Well guys my gauge pod came in today and i got my mech. gauges in today also( water temp, oil pressure, and volt, there all mechincal) i was just wondering where should i go though the firewall at? because i was looking for a hole in the firewall to run the hoses and couldnt find. I was looking for my oil pressure sender today so i can tap my new oil pressure gauge and i think i found it. its a 3vz-fe motor. Is it to the left of the oil filter with 2 wires going into it? when i put my car on the "on" positon but not running the oil light comes on with everything else but if i unplug it, it goes off and if you start the car it will still stay off is that the right one? also i need to know where to tap in for my water temp at? i let the car run up to its normal temp today and found a wire running by the radior cap up on the motor and when i unplug it my temp doesnt work but when i hook it back up it works. so Im guess that where i tap in for my water temp then. thanks guys for all the help

I think that mechanical gauges are a lot more dangerous, I personally wouldnt install them unless it was a racing application, but anyway- try a search, there is info about the wiring and senders. There is a hole in your drivers fender that you could run the lines through, just remove the splash gaurd in the fender and you will see it.

I just drilled a nice little hole in my firewall for my gauges and 4 gauge wire. If you do though, make sure you use a grommet.

ok sweet and im i right about where to hook the gauges up at?

[Camryshowoff97]

are you sure you got mechanical gauges? If your talking about spots where the wires are running into then it sounds to me like an electric gauge. My oil pressure gauge tapped into the wire off my sending unit because i have an electric gauge. Water temp if its mechanical im not too sure of but if its electric go off the coolant temp sensor.

Mechanical Temperature Gauges have their own sensor, sometimes put in the thermostat housing or something of the sort ... and yeah, they have wires runnin thru them

thnaks guys yeah there mechincal, do i take out the sensor by the oil filter and just put a 3-way there with by new oil pressure line? and for my water temp do i just take out that sensor and put a 3-way there with the new water temp. line? sorry guys i didnt mean tap i was talking about a 3-way lol if i take my mechincal ones back and get electric gauges do i still have to take the oil sensor out of the block and put a 3-way there with the new sender for the gauge there? same with the water temp?

ok well last night i hooked up my mechincal oil pressure and voltmeter. i took out the old oil pressure switch and put a tee there and hooked up the old oil pressure switch to the tee and my new fitting for the oil pressure line to the tee. the oil pressure gauge and voltmeter work good so now that out of the way. now i just need to find out where i can hook my mechincal water temp gauge up at. i cant find a spot on the motor to hook up the water temp line at?

is there an actual line of oil running to the gauge, or is it just a sender with a wire?

[400exboy2]

oil running to the gauge
