hi guys i really hope you can help with this one.
i beleive i have wired our gauges up wrong as the oil preasure gauge reads
backwards and oil temp only ever gets upto 60-65 degrees.
does anyone have a copy of the instulation/wiring diagrams?
i have looked on google for hours and carnt find jack.
i think there are 7 wires coming out the back of the gauges.

hopefully someone has used these gauges and know what is what.

Found this on another forum, Hope it helps...

This is for the Auto-Gauge (Halfords) oil temp gauge.

Gauge Lighting. (These wires are on the back of the gauge).
Thick Yellow - Permanent Live 12v,
Thick Purple and Thick Orange - Twist them together and connect to a switched live. (One that becomes live when you switch your lights on.)
Thick Black - A Good Earth.

Gauge reading. (These wires are also on the back of the gauge).
Thin Black - A Good Earth. (Twist together with the thick black).
Thin Green - To the Red (or sometimes it's white) Wire on your sender.
Thin Red - To a Permanent Live 12v (Twist together with the Thick Yellow).

The Sender. (These wires are on the actual sender).
Red (Or Sometimes White) - To the Thin Green Wire as mentioned above.
Black - I connected mine directly to the battery negative (-).


It's especially important that you connect the thin red to a permanent live, if you connect it to the switched live from your lights it will read slightly lower than normal and the needle will go up and down with your dimmer switch.
Do all of this correctly and the gauge should remember what colour it was when you switched your ignition off (although these Halfords gauges don't always remember no matter how you wire them up) and the temperature needle should still read with the engine/ignition off.

Cheers Jon. You're a life saver, we've been bashing our heads over this for a while now:thumbs:
