Using a standard ignition coil
I have an 87 Cherokee 4.0. I know the connectors look a little different, but thats easy enough to change... but has anyone tried hooking up a standard ignition coil?

Yes, I spliced in this oil filled coil no problem -
About once a year I had to replace the stock type epoxy filled coil witch is mounted to the block and would absorb heat and crack inside.

I just did a test of this to day
I soldered a small nail to the end of each wire
the nails fit in the connector just right they are small round holes
the blaster coil worked well now i need to fab it up permanent

Alright, I'll get some pictures in the daylight .
As the coil gets heated up the epoxy and windings begin to expand and contract as it cools causing the internals to crack and separate causing the car to die suddenly, but restart after several minutes of cooling untill there is no contact at all inside the coil windings which transforms the battery's 12 volts to the thousands of volts needed to spark the spark plugs.

Pics of the soldered nails. I knew the oil filled coils would replace the stock coils but got lost with soldered nails.

here is a pic
just unplug the stock coil and slip one nail in each hole on the plug
and you blaster coil is hot then plug the coil wire into the distributer
I scavenged some old plug wire part to make it work
