I have an IS tank on my 07 Standard. I am wanting to add a fuel gauge.
My current sender unit appears to have has its wires cut off.

Does anyone know how I could rewire the sender to attach it to (for example) an Autometer gauge? Specifically, what gauge wires to use, and how to.
Another option is to just replace the entire unit. They are not that expensive. But my question then is this:
Normally the wires terminate in a plug that is mated to the fuel sensor unit on an IS. This is not the case on a Standard. So since that is my situation, would I be able to cut the plug off, strip the wires, and then mount them directly to the fuel gauge?
I'm thinking probably not because power has to come from somewhere right? Not being an electrical type guy, any help would be appreciated.
