You hook a cheap coil to a switch in the cab of your truck then from the switch to the battery. Mount the coil somehwere under the car near the tip of your exhaust where your plug is. Then run a spark plug wire from the coil to the plug. Once the engine is warm, rev it up to bout 3 grand, flip the switch and watch the show.

Ya you will have to ground the coil to the frame but I think you have to run it through the switch first. It should go somethin like this,
Sparkplug-->coil---->switch---->ground goes to frame, positive goes to battery.
Does that help? If not Ill try and find somthin online like a diagram or somthin.

You run the groun from the coil through the switch and onto to frame...I think.
Ive never done this but had friends do it. Ill try to find somthin to make sure that Im tellin you how to do it right cause I dont want you to go try it and it mess up cause I was wrong

It won't work.
If you ground the neg of the coil to the frame the plug will never spark.
If you run a wire from the neg side of the coil to the neg side of the engine coil you have a chance of it working. Ignition coils MUST have their circuit interrupted regularly (breaker points anyone?) so that the magnetic field collapses creating the high voltage spike that makes the spark.

Don't see how that works, unless you constantly have power to the coil
Or you run 2 switches
If you run it like im understanding... Y on the switch.... one ear goes to frame, the other goes to coil.

Ok how about this...
You run 2 wires off your stock coil to the other coil
one for positive, one for negative
On the positive side, you put a switch inline with it...
So off from main coil... to switch, out to the second coil
You flip the switch when you want it to backfire..

There you go. Ive never seen it "complicated" like that but its probably the best way (the right way and the safest way lol) to wire it all up. Ive seen people wire the coil strait to the battery and the frame so Im sure there are more than one way to do it. But this way seems the "safest" way to mount flame throwers. Seems like one of those double negatives....safe flamethower.

My dad was telling me how he would let his car coast down this long hill with his friends when he was in high school and they would turn the car off and have it in neutral, and while it was in it he would pump the gas and flood the carb, and when he started it back up it would sound like a cannon going off. He told me the last time he ever did it, it literally blew his pipes from the car. He had to stop and go get them out of the middle of the road. By the way he drove a chevy, so they were bound to fall off anyways.
