You can find them on ebay at a reasonable price.

I personally would have an inline fuse between your tapping point (on the alternator) and the relay.

for example: Narva |
IN-LINE MAXI BLADE FUSE HOLDER (Blister pack of 1)

You can get 40amp maxis.

Otherwise Narva |
IN-LINE STANDARD ATS BLADE FUSE HOLDER (Blister pack of 1)

Relays keep the high current out of your switches, allow shorter power cable runs for less voltage loss. For example a relay allows spotties to come on with a switch from the high beams without adding load to the original high beam circuit.

Yeah,I was aware of this,I use them all the time, was just questioning the benefit of "new era" over a standard job

Aah, sorry. I think the New Era relays appeal because they look tough and full metal jacket and all that kind of stuff. Personally I prefer quality Bosch or Hella relays, they take up much less space and work just as well. Fuses belong in separate covered holders, not heating up the relay case.

Thanks for your replies..

I ended up running off the alternator, certainly the easiest point to get to, via a Bosch relay and a separate in line fuse. All working well.
