i am going to change the rocker cover gasket as it is leaking especially over the alternator. So I thought while I am in there I'll change the injector loom. I have seen a few about at the £30-£40 and then the original LR ones. So will either do or go for original.

£30-40? I paid £25 from Craddocks and they said "it's a Britpart box but the part is an OE"
And so it turned out. OE injector harness for £25.
