get rid of the gze... they are pretty much impossible to get to look nice, that's what i did.
helps if you have a microtech as they have nearly no loom, you can also run the body loom outside the engine bay (through the inner guards and under the rad support)
you'd be suprised how simple it is, it's just a fair amount of time required to move everything, and extend wires etc, butwould not be particualrly difficult for someone with not a whole lot of electrical skills (like myself)
moving things like the battery and washer bottle to the boot makes it a lot easier and neater, but if you generally relocate things that have wiring going to them it neatens it up a lot.
