Wema Fuel Sender Wiring

[Puffin]

I have just fitted a Wema fuel sender to my tank and have a wema fuel gauge to fit with it. Now comes the fun bit, wiring it all together to get it to work! The fuel sender has two wires, blue and black. The fuel gauge has a black lead that goes to the sender, a red lead that goes to the positive pole, and a blue lead that goes to ground (as well as yellow or orange for the backlight).

I am a complete novice when it comes to wiring. Am I write in thinking that the black lead that goes from the gauge joins to the black lead on the sensor and the blue lead from the sensor goes to ground? And I guess equally importantly, will I do any damage if I get it the wrong way round?

Help please.

There should be a wiring diagramme with the WEMA gauge. From memory when I set mine up, the senders work both ways round. It's easy enough to rig up without it in the tank and try it though.

Does this help?

The blue leads should be the signal, joined together not going to earth. Black will be both going to battery negative

Many thanks, sender and gauge successfully fitted and working!
