First your coil is wrong get part number msd-8231 it is meant for our trucks the 96-99 setup is picky to say the least. Second buy the kit from msd that makes the box plug and play I cut no wires on mine simply plugged in the pigtail harness and hooked up the box from there took five minutes part number msd-8877 cost is $31.99. Found all this on summit racing online it took longer to install and drill the holes for the mounting of the box!
Sorry, but I partially disagree on both counts.
The wiring harness 8877 is for someone who can't follow a wiring diagram. It consists of two oem ends and four blade connectors crimped on nine lengths of wire. The presumption is that if you can read a wiring diagram, then you can make temp splices otherwise, then by all means purchase the harness. Besides, I like doing wiring. It took me longer to wire up my efans the way I wanted than to install the fans themselves!
Now that being said. You may be on to something. I did look up 8877 on summit and made the following observation. I zoomed in on the picture of the IGN coil driver side of the harness. It doesn't look like it follows MSD's instructions. It looks like it plugs into A, C & D instead of A, B & C. Has anyone else noticed that?
As for the truck being picky about the coil, perhaps your right. The 8207 blaster is a hotter/faster coil than the OEM dropin 8231. In any event, you'll note that it's not connected to the truck's distributor just the spark tester which is not picky about coils. It should light up with any type of spark from any coil. I even use it on my kids quads/dirt bikes/sleds to trouble shoot spark issues.
Thanks for the ideas! Keep em comming!

What does the led light on box do when you turn on ignition or try starting?
****...there's a LED on the 6A? I didn't notice that! I'll go look in the morning and report back!
