Is there a part number or vender that would have a replacement condenser for this 2F 77 ignitor. Thanks to Mud member (aging fleet) who posted up the NAPA part number for the replacement resistor.

I've got this same/similar igniter. I'm trying to use it in a 73 FJ40 after installing a 2F engine with a large cap electronic distributor. Does anyone know how to properly wire it?
I'd start with looking at the 77's wiring diagram. Coolerman has a bunch of WD. There are free manuals for downloads. Chilton has OK/good WD too.

Thank you for the reply! The igniter I have, very similar if not the exact same to the one pictured (89620-60012) has totally different wire colors than those depicted in any of the wiring diagrams I have found. Additionally, the way the 73 FJ40 is currently wired for Pertronix in the DOA 1F engine, does not match the wiring diagrams I have for a '73. And that harness appears to be original... Not sure if trial and error wiring the igniter can hurt anything? Most confusing.
I wouldn't suggest trial and error. You can definitely blow an igniter that way.
Coolerman did a writeup, here I think, where he created a mini schematic of his igniter. If you can find it that may be helpful as to what wires go where.
On my 79 the external wiring to/from the coil/igniter assembly involved these these connections:
- 7v to 12v power from the ignition via the resistor wire to coil + (mine is heavy gauge black w/yellow stripe)
- straight 12v power to the igniter (mine is light gauge black w/yellow stripe)
- distributor signal + (mine is red)
- distributor signal - (mine is white)
- tach wire to ecc from coil -
There is also a wire from the igniter to coil -, that does the job of the igniter, to trigger the coil to spark. And a ground wire from the igniter (internal) to the igniter case or bracket (mine is green).
Of course your wires will probably be different for the 77, but you might be able to do some process of elimination to help with the guesswork.

Would you mind sharing your specific wiring setup to your igniter? Pics? Thanks in advance!
I'm not sure pics of my project would help much as mine is a 79 with a very different igniter, and much of the harness is now taped up.
Also, I don't know what's involved in a Pertronix setup, so maybe someone else can chime in if it would roughly be equivalent in wiring to an oem electronic ignition.
In the interim, my best advice would be to try and figure out which of the wires outlined above correspond to your harness as it is currently, then try to match up the loose ends from your igniter to the appropriate leads in your harness.
You'll need to reference your year specific wiring diagram to determine some wires and a voltmeter to determine the rest. See what voltage you have on the harness ignition-related leads with ignition switch on. 12v might be from the ignition switch, either directly or through a resistor in the circuit (with no current flowing).
Hopefully, by doing all that, you'll only have a wire or two unaccounted for. Then you can try to follow any unidentified wires back to its source to complete the picture.
It may be a little tedious. I did all that when starting with my cobbled wiring harness compliments of the previous owner. Little by little, I was able to correct it per the schematic from Coolerman, and then annotate it to include any mods I made along the way. Not fun, but in my case, necessary.

Thanks - Makes sense. I have yet to locate the Coolerman schematic. As a reminder, my setup is the Toyotq Large Cap Electronic Distributor with 2 wires, not a Pertronix which I believe has only 1 wire (not sure on that, though). I have DM'd Coolerman directly, but suspect he gets flooded for advice...
Here's the link to Coolerman's schematics -
In your case, start with the 73 schematic and see what may have been modified for your Pertronix. I'm not sure about this, but I was thinking the Pertronix replaces oem points with an electronic pickup using your existing distributor, not a one-wire HEI distributor that has the coil in the cap, but I could be wrong about that.
You may find that the Pertronix update to your harness may be compatible for the big cap of your new 2F, which requires an external coil and igniter to deliver spark.

Have you considered using an igniter and coil from a FJ60 designed for your big cap distributor?
When I did a big cap upgrade on my 79, I opted to replace my oem 79 igniter and coil with a used igniter and coil from a FJ60 (see pic).
That igniter/coil is simple, reliable and designed to not require a resistor in the ignition circuit. In my case, I deleted my oem resistor wire in the harness and I had to rewire the ends of my ignition wire and tach wire to match the new igniter.
Works great!
