Idk if this is a newb question. But looking to upgrade to ls3 coil packs. I have a 2000 ws6 with ls1 harness. Getting a set of katech valve covers with relocation kit that goes close to the fast fuel rails. Will the ls3 coils plug into my ls1 harness?

They will plug right-in, but remember that the bolt spacing is different so order the coil brackets for LS3 coils.

If you are using the Katech valve cover coil relocation kit, then yes you'll need to order for LS3 coils. There are 3 different bolt spacing's so order for the coils that you are using. http://store.katechengines.com/coil-...px?Thread=True

Yes I using the katech relocation kit. Just want everything fit and look nice under the hood. Plus heard ls3 run hotter then stock ls1/ls6
