Gauge wiring diagram.
 

Bought an oil pressure and oil temp gauge, but it looks like only the oil temp was ever setup to work.


I have had a search, but the majority don`t have pictures or are different.

So have to figure out the wiring, as they didn`t come with any form of diagram (was bought like that).

Here is the rear of each gauge, I`ll explain how its wired at the moment.

This seems to be the "master".
There is a power feed +ve to (S) and -ve to (-).
Sender goes to (+).
Then you have feed to light and light on gauge2 running from + and - going into red circle.

Red circle has feed from + and - from Gauge1.


This is why I`m a bit confused.
Going to need a pressure sender, then wire them in and it should be ok lol.

This look ok??

The above diagram is what a lot of gauges work on, but isn't the same as your first two posts, where you say:

It's the second and third lines above that I see as different?
Personally, I'd try as your diagram above.

You didn't say what make gauges? And do you have the senders?

Erm Dragon Gauge, and the other is the same I think.
I have one sender for the Temp, so what ever happens I`ll need a pressure sender.

OK. Assuming you can source the sender, (since not all senders work with all gauges:(), try the diagram as you printed it.
