I'm trying to install the wiring, relays etc. for a heated windscreen on my Discovery 300 Tdi. I've bought a Heated Front Screen Timer (PRC 6796), the dash switch (AMR 5177), connector plugs etc. necessary but haven't got a clue as to how to wire it all together. The dash switch has 5 connectors, Numbered 1-5, and the timer Relay has five spade connectors numbered, 2,4,5,6 & 8. The screen has two water-proof "socket" connector blocks, one at each bottom corner. Each of which has a live and earth lead.
(I fitted 4 x Auxillary Lights to the Safety Devices Roof-rack with no problems and installed the relays into an IP54 junction box because I was fed up with having to replace the Fog and Driving lamp relays due to corrosion. These were originally fitted on the inner wing but are now tucked-up safe with the other relays in the IP54 box.)
Could someone please help me with a diagram that an idiot could understand?
