hi, i am connecting up a temp, ammeter, and a oil pressure gauge, using a wood backing which fits into the off side glove box, my question is how will i earth the ammeter light as the temp light goes to earth through the sender and the oil light has a earth fitting on the side of the bulb holder will i be able to connect a earth wire from one of the other casings to the ammeter casing or is thier some other way. cheers

Yes.

Run an earth wire from the bracket clamp screws on the gauges to an earth point under the dash.

thanks bm, & mike, once again for the advice
