The led flasher won’t have any effect on the standard incandescent bulbs. Led’s Don’t daw much current and a normal flasher sees it as a bulb being out. I would just rewire using the online instructions and see what happens. Hopefully you didn’t fry anything on the circuit board.

Keep us posted.

Nothing super exciting, but I redid the battery cables with military-style terminals and some 2/0 cables from batterycablesusa.com. Pretty impressed with their quality and low price!

I’ve been trying to pay attention to quality on little projects like this, so dielectric grease all around, 3M electrical tape, and split loom over the cables.

Anyone have any recommendations for a good battery? I used a DieHard in my TJ and it’s been great, but the Sears in town went out of business about 3 months ago...

For regular batteries, liquid filled, I always buy Interstate Batteries. I even run them on my Dodge Ram 3500 diesel.
On my off roading Jeep, I run Optimas dry cell.

How is the Optima performing/holding up? I heard that their production went to Mexico a few years ago and they haven't been the same since.

I got dual batteries on my Jeep cj, red top runs the vehicle electrical and yellow top runs the winch, about 7 years old and still holding up good.
I think these are USA made.

That was over a decade ago. They're back to good quality now.

I had a little down time today so naturally I messed around with the wagon. I updated the to an TFI a while ago, but it still had the factory coil bracket that I cut up to fit the Ford coil.

Some cutting, grinding, drilling, and a lot of filing later, I ended up with this:

And here it is all mounted up:

While in the area I found what a factory looking black connector and a ring terminal that come off the engine harness right near the coil. The way I got the Jeep the ring terminal was connected to the coil mount and the plug wasn’t connected. Anyone know what these are for? Something to do with the ballast resistor?

The ignition schematic from the '90 TSM shows a capacitor that connects to the positive terminal of the coil. Is this the black connector I'm seeing?

Another question for the FSJ experts: I'm in the middle of putting in an electric fuel pump and when taking out the old mechanical pump I noticed it has a return line. Provided I use a fuel filter with a return before the carb (which has its own metal return line), I can remove the metal return line from the old mechanical pump, right?
