On the Mallory 6AL, it has two different methods you can use to wire it up to trigger the ignition. One is a single wire that's connected to the distributor, or as the instructions put it "Connects to points, electronic ignition amplifier
output or to the green wire of a Mallory timing accessory" and the other, two-wire method that uses a magnetic pickup: "plugs directly into a Mallory distributor or crank trigger. It will also connect to factory magnetic pickups..."

So what method do I wanna use for my FJ62?

I think that is the one I have. I ran it to the coil and it piggybacked onto th ecoil with the stock ignition in place. it worked great but when it died it took out the stock ign as well.

You saying that you connected the two stock coil wires to the dual wires on the 6AL? I was thinking that'd be the best way to go, but just wanted to make double sure so I don't F something up when I install it. Thx bro :D

I would guess you would hook it up using the factory pickup and delete altogether the stock ignitor. the stock ignitor is really going to take a beating if you are piggybacking it in addition to the MSD. I would most definetly run it this way, and keep the ignitor and a second distributor pickup with you for when the MSD craps out. Every one I have had personnally or seen used on friends cars/trucks has at one point or another crapped out.

EDIT, dont think that deleting the stock ignitot altogether would work... thinking FJ60 for a minute there...

Good idea. I brain farted and forgot about the igniter (I'm over 4000 miles away for cryin out loud). Is the factory pickup a single wire or dual?

red and white wires IIRC, so two.

Why will the MSD kill the ignightor? Funny enough mine died and the MSD died soon after that. Connected?

did you run it so that the ignitor AND the MSD were connected to the "-" side of the coil? Or did the wire from the ignitor formerly connected to the negative side of the coil trigger the MSd and remain unconnected to the coil?

Cool. I remember trying to trace the wires before but getting lost in the tangle. I take it it's the trigger wires from the distributor, the ground wire, and the ignition-switched positive lead that make up the four wires on the igniter?

IIRC I ran both to the neg side of the coil. I called MSD and that was how they said to run it but eventually it fried the system but it took around 20K to kill it.

No, the FJ62 distributor has two magnetic pickups. I think one acts as a crank position sensor for the ECM, or maybe gives RPM input since it has two teeth(since the cam and distributor turn half as fast as the crank), and one with the red and white wires that is for the ignitor.

dd113,
What did you have triggering the MSD if you if you had the ignitor/coil hooked up as stock and functional as well?

Delete the stock ignitor entirely..

The MSD replaces it

Use the stock 2 wires coming out of the dist for signal..

I am currently having ignition problems with my MSD blaster system. It appears that the starter is drawing too much voltage and Not allowing the MSD to trigger the coil..

Sucks..

IIRC you cant delete the ignitor on the FJ62's since it serves as the ignition module to convert the ECM signal to the actual coil firing too. what I would guess should happen is to use the wire coming from the ignitor to the coil to trigger the MSD(single wire trigger) and not attach it to the coil. that way the ignitor is not triggering both the coil and the MSD box ignition pickup. I think the extra current load b/c it had to trigger the coil and the MSD caused the ignitor to go tits up.

Jason, as for your issue, I would think that you have a bad connection in the wiring, or maybe at a battery terminal or maybe even a bad battery. the battery should not drop voltage enough to prevent the coil from working. try a relay to power the coil directly from the battery.

So basically wire the box inline between the ignitor and the coil? That was my original thought, and it's sounding like that's still the best way to go. I was just unsure as to whether I wanted to use the two-wire method or the one-wire method. Sounds like my original plan is the way to go, only using the one-wire method instead.

With the positive lead from the ignitor to the coil unused (the Mallory instructions specify to have ONLY its wires connected to the coil), I could safely just insulate the ring terminal to keep it from grounding and tuck it away somewhere, right?
