Okay so I installed the Hughes plenum fix. Everything went well. Only problem is I noticed tonight that my truck was running rough. I turned out all the lights and saw that one spark plug wire was arcing on the exhaust man. What is the best way to get to the cap to replace my wires? It's way back in there.

 

just reach back there and feel it out. thats the easiest. you gotta lean alot and make some goofy faces trying to find everything. there are two screws on either side, phillips head undo those and pull the cap up. and replace as usual

 

Oh. So what your saying is pull my cap and attach the new wires then install the cap back on?
