Don't sweat the install it is very easy. After you do it once it can be done in ~30 minutes. You just need some basic tools. Ratchet, 10 or 15mm deep socket (can't remember which), extensions, and a swivel for the ratchet for the bottom manifold nut on the passenger side. It's a piece of cake. Drive you car up on ramps put the rear on jack stands, and get under there. MIL eliminators will turn of your engine light only from the O2 sensors since you don't have cats. Unless you plan to get a chip someday don't waste your money on MIL's a custom tune can turn the light off for free.
