200tdi starter relay

I had a 2.5 diesel freight rover engine in my 1983 110 originally but have replaced with a disco 200tdi. I am using the original six pin relay but a little confused of wires going into it, masking tape has either faded or come off over the four years to this point. If anyone can help I will be very appreciated.

So on the relay:-
Pin 30 - Red - Live
Pin 86 - Black - Ignition
Pin 50 - Black/Red - Red/White Main Loom
Pin 87 - Red/Yellow - Glow Plugs
Pin 85 - Brown - Earth
Pin L - Brown/Yellow - Dash Light

I am not worried about colours as this how it was when I bought the 110. This is my fourth year and nearly ready to go on the road. A few other problems like oil cooler hoses not long enough, I fitted silicone hoses with clamps but unfortunately they leaked so back to the drawing board. All the best.
