Suggest that you change wires with plugs...and, go one wire at a time. I generally gap all the plugs first (using OEM Champions at .035), then lay out all of the new wires on a table to check length vs. number when I remove a wire from the car.
After removing wiper arms, (may need a small wheel puller or battery terminal puller to get them off), then remove cowling (4 screws), and, if your arm is big, remove the front two struts that hold cowling in place as they will cut skin easily...(on a Gen II, must remember to put ground strap back on the strut on the left...can't recall if this is the same on a Gen I).
After disconnecting wire from plug, but before touching plugs, I blow out each site with air from compressor, then break all the plugs free...leaving them in place while I reblast them with air. As I remove each plug, I label it, check hole for debris, then gently install plug BY HAND after applying a small amount of Copperslip to the threads.
Once all are in place, I torque them to 18 ft-lbs (subtracting 10% of torque from the recommended 20 ft-lbs due to the antiseize)...noting that I keep a 14mm thread back-tap handy in case of a thread problem.
Then, I generally start on the left side, and go one wire at a time, noting that I do apply a SMALL amount of di-electric gel inside the connectors on each end of the plug wires before I start the exchange...and, noting that I clean plug tip and coilpack electrode before making each connection.
It helps to have multiple lengths of extensions and a universal to get the job done. As I have a "weasel-arm", I really don't have to remove the heater box (4 screws if I remember correctly)..but it does help to do so, especially on the first time.
When wires are in place, check plug and coil pack connections one last time...AND, do a visual check with a small mirror to confirm that number on coil matches plug wire number. I should note that I place the wires in the retaining loombs as I go. Reinstall cowl.
Be sure to check manual, but I believe that the center point of the right wiper blade should be 22 mm above the cowl and the left 40 mm...again, check manual also for torque on the wiper arm retaining nut.
If heater box removed, reinstall, and, if your Gen I Viper has not had the throttle cable adjustor button TSB. resync throttles now, they fire that baby up and FEEL THE POWER.
If I've left something out, hopefully others will correct same...and, I do realize that this is a bit wordy.. please do not take offense at the step-by-step approach as it was written for a non-experienced person ( BY an a equally non-experienced person !!!)
Have fun !!!
Yep...Steve you did leave something out...save your pocket change in advance to put in the "SWEAR JAR" There is always that "one" that will not cooperate.
