This is a dumb question but I want to do this once and do it right. My temp sensor is bad so I just bought the 3 gage set of volt, water temp, and oil pres. Where is the oil pressure sensor and where is the temp sensor ??? The gages I got are not electrical. The guys at the auto parts store said the electrical ones are more problems so I opted for the mechanical ones. This is my 97 4dr. Sport with the 1.8L. I know most of you are thinking I'm retarded but I want to do this install right. Thanks.

Nevermind, found them both. Since the ODBII motor uses the existing temp sending unit I have to replace it anyway. I will have to find a place to TIG weld the extra mech. temp sending unit. Has anyone else done this or am I biting off more hassle than it is worth? The new gages are realy small and light up blue. I foung that the little tray under the radio is PERFECT to fit them in. I had to cut out the bottom but they will fit perfectly. Any advice may help.

The temperature gauge probably came with a bunch of adapters that screw into one another - you could weld one into the radiator header tank (if it's brass) - if not the pipe that runs from the radiator top hose to the back of the engine should be a useable place.
For the oil pressure gauge, make sure to use a T fitting so that you retain the existing oil pressure light - if your gauge came with a nylon line, discard it and get 1/8" copper line (do not use brass, it work hardens with the engine vibration and becomes brittle), the nylon lines slip in the ferrules and eventually leak. On my Swift I installed the oil pressure and ampere meter from an Equus 1-1/2" set above the radio and had a leak at the gauge end that dripped oil into a CD/MP3 player and destroyed it.
FWIW - electric gauges are easier to install and just as reliable as the mechanical ones.

Thanks for the advice. I'll use the copper line and a tee fitting.

Too bad you already got the gages. Running oil lines into the cabin, even plumbed with copper line is still a chancy and sometimes problamatic install. The electrical oil pressure gage's ( at least Autometer ones ) use a remote sending unit that you run an oil line to ( preferabley braided ss ) and mount in the engine compartment. Then it's just one wire into the cab. NO chance of oil spewing about under the dash.

i've been running the nylon for 6 yrs. never a problem

One more thing, the oil pressure sending unit threads in the block are of some metric pitch that I had a real hard time finding an adapter for. Maybe you could find an adpter at a ricer speed shop. I ended up just retapping the threads to 1/8 npt with a bottom tap. Made fitting everthing just a home depot or pep boys deal.

My first gauge install used nylon and I never had a problem, my last gave me no ends of trouble, and I discovered there are different qualities of 1/8 nylon line.
The one that leaked into my head unit was a relatively thick walled line that was supplied with the Equus gauge set.
|removethispart|@bentparts - I've yet to see an electrical gauge set in the small 1-1/2 inch style - which is the only size that can be neatly fitted into one of the DIN radio slots (50mm - 1.97 in high) - the next size up is 2-1/16 inch, followed by 2-5/8 inch.
If you do know of a manufacturer who makes electrical gauges in the 1-1/2" size, I'd love to hear about it - because I'm in the market for oil pressure & voltmeter.

The thread size is M10 x 1.0, I once made a temporary fitting from an old moped spark plug.

The fitting that came with the gages is the right size already ;) I got the lights and voltmeter wired up already. The temp sensor and oil pressure will have to wait. I have to get a new step drill, I smoked my old one on my last project. I also will have to tig a bung on the water tube for the probe. The computer needs the old sensor to run but all will go well. I got the same gages as fordem. They seem to be pretty good and they fit perfect.

The computer uses a different sensor to the dash gauge.

Where is that one at?
