Hi Guys,
Firstly before people think I am being laxy I really have read a lot about this etc...
Basically I have a K Jet DX engine in my T25 Camper and due to not knowing the condition of the engine I wanted to keep an eye on its temperatures.
I bought a set of Audi Coupe gauges from ebay which arrived today and was wondering if I need any of the wiring loom?

What is the relay for? Should I keep it?
Following this guide:

Thanks all
