What do you guys think of the wiring kits?

[hpcgmc]

My wiring is pretty trashed and I need to re-wire my tail lights before I can get the truck on the road. I'll need to do my engine compartment pretty soon. I see a kit from LMC for about $700. Pretty pricey, but if it's all "plug and play" and easy to use, I might be willing to spend the money. Has anyone used this kit or a similar kit?

Anyone know if I can buy the kit and just use parts of it now, connecting into the stock harness, until I eventually replace all the wiring?

Does Brothers or anyone else have a good kit?

Thanks!
