I bought my elements, and did a test run earlier.
Switches installed and fuses 45 and 37 are also installed, switches illuminate and light comes on when they are switched on, cool.
Under the seat there is room for the black and grey connectors from the heating elements to plug into the cars loom, great.
Problem i have is that there is a 3rd connector comming from the heating elements and its a small 2 wired one, colours are red and red/black, where does it go? Also its on a seperate tail on its own, like it plugs somewhere differant than the block under the seat, only 6 inches away though.
