I recently had my Hooker LT's installed and now I am going to install new plugs (NGK TR55) and OVC taylor wires. Does anybody have instructions on this to where to put the wires. How long does it take to do this and can all the plugs be accessed from the top of the engine bay

 

It should be pretty obvious where the wires need to go. Just take your time and measure twice and you should be good.
I did MSD regular wires (not OVC) and it took about an hour with me routing wires very carefully. I actually routed the last 2 on driver side up over the valve covers to keep from burning them, the rest seem just fine. I routed the last 2 on the passenger side under the motor mount. I don.t have AIR or EGR or AC so you might have more stuff in the way than I do.

 

I have the exact same set-up but only with Jet-Hot LTs I'm putting in. Take your time and measure twice as revtime said. No mistake is worth a few minutes saved as it will cause time lost. Plugs SHOULD be able to be accessed from the top with the headers without much problem or any. I dont have instructions due to the fact I'll be doing this during this week. Sorry . Shouldnt take more than an hour or 2 if that. I've done it on a few other cars however. After looking at my taylor OVC wires, it looks as though they are already the appropriate length . Guess I'll find out shortly.

 

This is how I did my Taylor's. I got a set of Made for You wire looms and dressed the wires nicely over the valve covers. Like everyone said measure twice and cut once. Plug access is going to vary with different header manufacturers. I got to some of mine from underneath. Just be patient. I would also invest in some heat sleeves for your wires. You don't want to burn your wires on hot headers.
