Air/Fuel should be thrown away (unless it's a wideband). Oil pressure gets Tee'd into the oil pressure sending unit fitting above the oil pan on the pass side. And the water temp can go in the upper radiator hose (how I did it) or drill and tap the manifold near where the stock sending unit is. Or find an adapter if you can.

Oh poo on you Chris. I still say SOME form of AFR gauge is better than nothing at all.

Do you have the guages yet? If not, they will have directions with them.

are these name brand? more specificly, do they have a website with the instructions listed on line? if we knew what kind of signal it was looking for on the distributor we might guess at what you'd need to do to hook it up.

jam random wires into the wall socket

most gauges have 1 red 1 black wire, that for you to tap into 12v ignition and ground. Another wire will be going to the sender

what no one asked you is if they are mechanical, or electrical gauges. And unless its a wideband 02, do take c-rads advice and place it in the garbage..... i.e. ebay

tachometer signal is on the small white plug beside the ECCS plug, it's the yellow/red.

As for wiring it...USUALLY they'll have 3 wires. Red, black and some other colour. Red is usually power, black is usually ground and the other is usually signal.

Are you sure absolutely no instructions came with it to tell you which wires are which on the tach and other gauges?

As for the oil pressure, gotta know if its mechanical or not first.

Your water temp should have come with it's own sensor, so you just need to put that either into the head, or in the upper rad hose.

As for O2, if it's narrowband, then you hook the signal up to Pin 29, it's a white wire on the ECCS plug. Or if you wanna hook it up to the wire in the engine bay, it's the shielded one in the middle, again, also white.

http://www.impactblue.org/cont...iringThat's the ECU pinout.

if your oil pressure gauge is mechanical, you have to tee it into a source, I don't know where cause mine is electrical. If yours is electrical, then you'll have a sender. The stock sender is on the intake side under the alternator. it's a small plug dealie that screws into the engine. You'll most likely need an adapter. You can get an adapter that can take two(basically a T) or just get an adapter for your aftermarket gauge. The thread pitch of the stock one is 1/8 BSPT (if memory serves me right..but it might not...)
