okay I should have picked that up and didn't. I only spent a few minutes gathering the parts anyways so I'll just take them back tomorrow. I plan on keeping the 8mm wires though since my Jeep seems to run just a touch better with them.

what is everyone gapping their plugs to when they do this mod.

i pulled some plugs to check my mixture and realized the gap is a little small 35-40 do you think we could jump the gap size to 55-60 since we have a lot more spark energy available?

With my new coil 0.045" was perfect.
There is no need to (and you really shouldn't) gap above that.

question I looked up all new parts at NAPA and the total was around $150.00 then I looked at a juice box set for $80. any advantages between doing it with the parts from NAPA over the juice box set.

The "Juice Box" people took the instructions written out by Jeep Hammer (a guy on the boards here) and then substituted the cheapest crap they could to get the price down.
This upgrade is about using "premium" parts, not junk.
The Juicebox kit will work, I've seen it before, but I don't trust the components.

Thanks. Thats what I thought. I agree about using the best parts, and will follow through with the stuff from NAPA. I would rather do it once and do it right.

I finally did this mod today using all the best Napa parts. Best money I have spent in ages. Had to fatten up the carb a full turn. I am now experiencing power all the way up to 4k rpm ( I let off at 4k I was skeered ) and a very smooth idle. It also started much easier than it ever had. Only thing I can compare it to was the Jacobs ignition I had on my CJ but this still beats it due to the fact that it pulls at a higher rpm.

I have the BWD Ford E-Coil and pigtail and am wondering how to wire the pigtail. My jeep connector has a yellow and green wire (yellow connects to stock coil on side that says "BAT"). My ford pigtail has 2 green wires (-) on one side and a red (+) on the other. So which way do I splice the pigtal? Thanks!

You have two green because one is for the tack.

The yellow on the stock that says "BAT" is the +, otherwise corresponding to the red on the Ford. I'm not 100% positive on the green wires but I would think both are grounds, one to the chassis and the other to the ground side of the circuit. As long as the coil grounds well to the chassis were you mount it and you use dielectric grease on the surface then you can wire both the green wires on the Ford coil to the green on the Jeep.

If you ground that green wire your going to burn your coil

I plan to mount the coil using two "L" brackets and attach it to the inner fender. How can I wire it so I don't ruin the coil?

If we are keeping our old coil, do we still gap to .045 ?
