What gauges can i install?, 94 ST Options

[mgnt232]

I have a 94 ST 7afe. and i want to get some 52mm gauges to go on the A-pillar. But i really dont understand how any of them hook up? Like oil pressure? can i do that in an ST
I am looking for something cheap, not a wideband air/fuel $300 thing.
If anyone could give me some pointers, on an ST installation id b very happy
I want to find 3 or at least 2
thanks in advance-!

oil pressure, oil temp, and voltage. all cheap. get electronic gauges not mechanical ones.

They usually come with 4 wires, 1 for 12V power (I use the Radio wire), 1 for ground , 1 for the wire source on what your trying to hook up, and the other 1 is for your headlight switch(optional can be left disconnected).

For oil pressure you will need a new oil pressure sending unit which usually comes with the gauge and then an adapter that will fit that gauge into the fitting for the 7A because Toyota likes to make stuff that doesn't work with anybody else.

Oil temp is a pain in the ass, I wouldn't even bother with it.

If your lazy, you can get the cigarette lighter plug in battery voltage display. Just plug it in and you got voltage metering!

for the voltage meter, a 52mm one, would i just run a pos, and neg? just as easy as that? and maybe the headlight switch? thanks-

Buy a sandwich adapter for the oil temp and oil pressure. It screws on where your oil filter is, and then the filter screws onto that. The sending unit fittings screw right into the two outlets on the sandwich adapter. Then you just run the lines in through the firewall and up the A-pillar. Oil pressure and oil temp are real easy to do.

Water temp is easy too, if you don't want to look at the idiot gauge in the cluster. Cut the upper rad hose and stick the sending unit in-line, then run the wiring back.
