Anyone know how to wire a big cap fj60 distributor to a late fj40 semi electronic igniter. Any help would be greatly appreciated.

What’s that one off of Dale? A 78 or 79 would be plug and play.
I can't help you with the wiring for your early generation igniter.
However, I did a FJ60 big cap upgrade on my 79 recently and opted for a matching FJ60 igniter and coil. More reliable and no need for a resistor in the ignition circuit.
And the wiring for my 79 was easy, but it wasn't exactly plug and play for the used FJ60 gear I found. They both used the same 2-pin distributor connector as the 79, but the power and tach connectors were a bit different.

Part number says 78 to 79
This is the oem igniter I replaced on my 79.

Not sure if this will help, but there was another member who had a similar question today about wiring an igniter that looked a lot like yours to a big cap distributor. I relayed some info about the oem igniter/ coil wiring on the 79, which will be different than yours, but maybe you could use some of it to get started.
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 (resistor in your case) 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 your 40, but you might be able to do some process of elimination to help with the guesswork.
Coolerman also has a schematic that he created to better understand the internals of his igniter. It helped me.
