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?

The electrical system update is coming along.
I needed a place to mount relays and circuit breakers so I fabricated a heat shield for the battery that can mount relays on the battery side to protect them from the engine heat. It is held in by the radiator bolts and a bolt under the battery. I painted it with engine enamel and faced the backside with adhesive heat shield material. Not yet on the pictures below is the revolution electronics fuel pump controller.

I also stripped the gas tank skid down, strengthened a few areas, and coated the whole thing with POR-15 and then some POR undercoating. I added some flat bar to the mounting holes along the frame and some 12 ga. sheet to the upper inside face to mount a Holley Red electric fuel pump. Image
Image
Image

Because that area is pretty close to the exhaust, I made a heat shield from some aluminum sheet, and faced it with leftover heat shield material.

In theory I have enough room for the driveshaft to not contact the pump or heat shield, but I’ll have to test fit to be sure.

Here is the battery box I’m using: https://www.summitracing.com/parts/tgi-301347-kit/
I picked it because the back face of the box is flat with no protruding bolts for the air intake hose which runs right there. I welded a few tabs to the battery box so that stock mounting locations are used.

To finish the recap of the past few months, I started installing the twin stick kit from RockLaurence. Cutting a hole in your rust-free floorboard is little nerve wracking!
