| | Re: spark plug wire replacement
I actually just did my wires and plugs today (well I tried the wires but the ones autozone gave me were too short)...if you pull all the wires off you can fit a flathead screwdriver under the little tabs on the brackets and they pop right off.
As for the firing diagram, mine has one under the hood right where the wires hook up. Might want to check that if you haven't already.
