aftermarket gauges questions

[Firstoff]

so i just went and bought the mechanical oil pressure gauge, the volt gauge and the water temperature gauge, where am i supposed to hook up the oil and the water temp gauges. the volt i understand, and id like to mount them right behind the sun visor of the sun visor, about half an inch in front of the windshield, is there anything for the mounting screws to grip there or will it go through the roof.

For the oil gauge - You need to get a "T" adapter to go in the the oil pressure sensor port.

For the coolant Gauge - You need to get a "T" that fits into the top radiator hose.

Im confused:

Id like to mount them right behind the sun visor of the sun visor, about half an inch in front of the windshield

Behind the sun visor, of the sun visor?
And in front of the windshield? You mean outside the car?

You should get electrical gauges not mechanical, it will make things 100 times easier and safer.

Mechanical gauges are better for under the hood applications. Otherwise your bring potentially hot and dangerous liquids into the cabin of the car.

In regards to hooking up electronic gauges, I have an aftermarket oil temp, oil pressure, coolant temp, and volt gauge in my cb7.

On the back of the block under the intake manifold there are drain plugs, both for oil and coolant. I had them tapped for 1/8" NPT. The coolant & oil temperature sensors was inserted directly into one of the drain plugs. For oil the oil pressure sender I had a 2ft hydrolic hose made with 1/8" NPT fittings on each end, one end screws into the factory pressure sender location with a 1/8"NPT t-fitting (bought from home-depot), with the factory and aftermarket senders connected to the t-fitting.

Here are some pictures of the drain plugs I am referring to:



After tapping for 1/8" NPT:



Here are the locations of the plugs (oil is below the filter, coolent is to the right of the filter: (The oil pan gasket has been replaced since these photos)




Here is a picture of the hydrolic hose, t-fitting, oem & aftermarket oil pressure senders:


Here are pictures of where the senders are mounted to the engine:



Here are where I mounted the gauges:


As for the wiring its really simple, one wire is ground, one is power, and one is signal. You only need to run one wire from each sender to the gauge, then you tap into existing power and grounds at the driverside fusebox, for the lighting just tie it into a circuit that activates when you turn on your running/parking lights (but don't connect it to the dimmer knob/circuit as the load from the extra lights could cause the knob/switch/relay to burn out.)

I hope this helps!
