Summit CDI install on a 79 CJ5

Just bought this off of ebay. The old style Summit CDI suggested on this forum by "JEEPHAMMER". I am pretty limited when it comes to wiring and need someone to spell out for me where to connect the wire that should connect to the ignition switch as shown in the picture. Everything is stock except for the "team rush" upgrade. It's the inline 6 motor. _57.jpg

The red wire at the top should connect to the red with tracer wire that goes to the existing coil positive. This wire serves a number of items under the hood and is live in run and Start only. The thing to watch is that you connect BEFORE any resistor wire you have in there, in other words you connect to 12V and not 7V. If you have an electric choke wire it will be red with tracer and be in the loom before the resistor.

Use the big red with white tracer wire between the firewall and old module.

No start. . . here's what I have. I tried hooking up the red wire to the old + coil wire (no start). So I tried cleaning it up. I took the old coil + back to the wiring loom and found the splice. Removed the splice and cleaned up the connection to the starter solenoid. Then routed the red wire to the starter solenoid and hooked into the smaller positive post (checked for 12v source with key on). I bought the MSD part#8869 adapter for between the module and the distributor. Black and Red are ran to correct battery terminals, orange is going to coil positive and black(smaller) is going to coil negative. Yellow is hooked to my tach, and white is capped off with a wire nut. I have the module set for 6 cylinder by having switch 2 down and switch 3 up (1 and 4 are still down). And I have the rev limiter set to 0 (4500 RPMS). Still .. . no start.

I think I have it figured out. . .I think switch #1 needs to be up (see figure 2 on the top of page 3). http://static.summitracing.com/globa...sum-850600.pdf It says "ON" next to the #1 switch. . .

Your old coil wire only has 9 volts or so when running because it uses a ballast wire. Like everyone else says, you need the red wire with the white trace that goes to the old ignition module for 14 volts.

So even with the coil splice removed and hooking into the wire the coil + was spliced into? I followed it through the loom and it looks like it all ties into the red w/ white tracer your talking about.

Still no fire. . . Cut the red with white tracer wire going to my old module and hooked it up to the new using the little red wire. Checked and rechecked all my connections. Rechecked that I had the box set for 6 cylinder. Nothing. . .
