battery relocation kit

[Niall]

and its ok not to run a earth from front to rear? no issues there?

No all you need to do is run an earth from the neg terminal of the battery to a clean secure place on the body. At the engine bay end, any earths that went straight from something to the battery (alternator for example i think), you just need to run these to the body. Theres no point in running a earth wire all the way back as the whole body is an earth so make use of that!
