All good cheers
Thanks for the offer of parts but now I’ve half an idea what I need I should be able to find the parts from work.
Knowing what to look for is the thing now lol
Still i’ve found out a 30amp relay, as said diffo pin order but the 4 numbers are the same 30/85 etc

I’ve just dummy wired it up and the main 87 pump output goes live with ign on
But just a thought as its earth feed is via the ecu shouldn’t 87 only go live when cranked or running?
Or have I just wired it wrong lol

Also I've just bought a reel of 2.0mm 25 amp 12v cable
Is that ok to use for the main pump + cable?
