Are you getting driveshafts from Adam's? They do nice work too.
I went with Tatton's this time around. Less expensive, no tax and free shipping. Besides, after my recent towing experiences I don't want to have to flat tow it back down to another shop. I'm swapping out all of the strap style yokes for ubolt style at the same time. Shafts should be here this weekend.

Drive shafts arrived today. I also picked up a battery and cables. I have some weird lighting issues happening (dome and under hood lights on constantly even with key off, front turn signals on only when switch is positioned to parking lights, turn signals off when headlights on, only some dash lights work when key is on, no gauges light up when switch is turned all the way, turn signals don't flash, brake lights don't work etc) I need to pull the light switch and verify all of the connections. Hopefully the electrical issues are only related to the lighting circuit.

The fuel pump kicked on so I bumped it a few times to prime the line. Not as loud as I thought it would be and definitely quieter than the Holley red pump on my other CJ.

I'm still waiting for my Yokes to arrive, then the driveshafts will go in.

Nice, he makes some quality driveshafts! I was attempting to cut and weld an xj shaft to use as my rear, but the captured ball area was wayy to worn out so went with tattons as well. Where did you get your yokes from ?

Yokes came from Rusty's, way cheaper than anywhere else.

I've been trying to figure out my lighting issues all night and found a bunch of pictures of the Jeep switch/painless wiring and they were all different. I wound up pulling all of the wires off and taking the headlight switch out of the dash.

I hooked the positive battery cable up and my parking lights/tailights and right dash turn signal lamp came on?!? Without the headlight switch wired up, now I'm really confused.

The dash right turn signal turns off if I reverse the wires on the back.

Could the LED bulbs in the turn signals / parking lights and tailights be causing the issue?

My dome and underhood light constantly on is an incorrect ground issue, that one was easy.

The LEDs could very well be the problem. They can back feed and act all kinds of funny, I had a courtesy light on my truck that wouldn't turn off and come to find out the led was back feeding and staying on.

I pulled all of the small LED indicator bulbs from the dash (r/l turn, highbeam and idiot light for tbi) and checked for proper wire orientation. The left turn indicator was wired backwards and now that they both are correct they both stay on with the pos battery cable hooked up and key off.

Not sure how the turn signal circuit is getting power with the key off and battery installed.

I replaced the front turn signal LED bulbs with standard ones and now the tailights come on with the key off, headlight switch removed and battery installed. I pulled fuses one at a time to see if the system was getting power from anything else and its not. It all turns off when i removed the hazard/dome fuse.

Ok, I rewired the headlight switch according to the painless diagram.

Battery connected, key off And the tail lights are on. Headlight switch in parking light position and I have front turn signals with no tailights. Headlight switch in headlight position and I have headlights and taillights but no park/turn and no flash when turn signals activated.

Starting to regret these LED's everywhere!

Also, with the key forward the fuel pump primes but I have no wipers, blower motor for heat and my overhead fan doesn't power up. Electrical is not my strong point.

Turn signal section and ignition section are wired correctly per the painless manual.

I contacted Painless and they sent me two diagrams, one of which I used to wire it originally. So I used the second one as reference this time. I separated #729 and #727 and installed. Now when I have the battery connected nothing comes on except the dash turn signals, when headlight switch is in parking light position I get front turn signals only and no flash with turn signal activated. When the headlight switch is moved in between the parking lights/headlights I get taillights on only. When the switch is in headlight position I get headlights and now all gauges backlight.

With the key off I still get over 8v at each of the dash turn signal indicators. Not sure why there is power there if the key is off.

I tested the light switch in different positions and failed to get power to the tail light terminals when they should be activated (with the switch in parking light and headlight positions) so I ran out and bought the chevy style switch that painless recommends. For $15 its worth a shot.

I found a disconnected 12v wire to my speedo gauge lights which accounts for the lack of lighting on that gauge only. Still have to figure out why my dash turn signals have power when the key is off.

We'll see how it goes tomorrow.

Ok, its not the switch.

Battery connected, ignition and light switch off I have 8.5v at both dash turn signal lights (wire #737 & 738 ) keeping those indicator lights on constantly.

Battery connected, ignition off and light switch in parking light position I have power to front turn signals (#725 & 726) but nothing to the taillights or side marker lights which should also turn on.

Battery connected, ignition off and light switch in headlight position I have power to headlights, no tail lights, no brake lights and no flash or turn signals or side marker lights.

I am using LED flushmount tailights (tail, brake & turn). I have used the standard and LED style flash relays during testing.

LED bulbs are wired into #725, 726, 729, 748, 749 & 756.

I pulled the switch off completely and connected the battery to test voltage between the power wire and all of the others in the light circuit present at the switch. Testing between my power feed (728 ) and the following wires at the headlight switch with battery connected resulted in the following:

728-707 = 12.67v
728-729 = .193 (tail/brake lights)
728-727 = 12.67v
728-730 = 12.67v

Does that mean that the ground is poor for the rear lights (728-729)?

With the ignition key forward I also do not have wipers or blower motor operation.

Gauges work, fuel pump works with ignition key forward.

I connected one of the constantly hot dash turn signal wires to the speedo light and the flash relays started cycling which is has not done before even with the turn signal level activated.

Have you double checked all your grounds? You can get funny things like that happening when a ground isn't connected. Just an idea.

Ok, with the brake switch connected and the ignition off, headlight switch off I get taillights on. Brake pedal depressed and I get brake lights. Once I move the headlight switch to parking lights position I only get front parking lights on the grill, no tail or brake lights. Once I move it to head light position I get headlights only, no tail, park, turn or brake lights.

I'm tempted to cut all of the LED's out of the harness and wire in the old style flush mount lights.

I searched and read nearly every thread on headlights switches last night and started back on it again this morning.

The headlight switch is grounded to the dash. I sanded off the primer on the back of the dash where it makes contact and I used a star washer in between to ensure positive contact.

Utilizing this wiring diagram with the battery connected / ignition off I get:

Tail lights - headlight switch in off position, brightness is controlled by rotating the headlight switch knob and they turn off when it is turned all the way to the right. Dash turn signals still remain on constantly. Voltage at the dash turn signal wires increases from 0 - 12.65v when rotating the headlight knob from right (off - 0) to left (on - 12.65v) and voltage stays at 12.65v when I turn the knob all the way left to click the dome light on.

Front grill turn signals and dash lights only - headlight switch in parking light position. No flashing when using turn signal lever.

Headlights and dash lights only - headlight switch on headlight position.

No brake lights when the pedal is applied.

With the dash turn signals power feed removed I get taillights(brightness controlled by rotating the knob) and brake lights when pedal is applied. No brake or tail lights when the headlight switch is in the parking light only and headlights position though.

I still can't figure out why the dash turn signals would have constant power. I also can't figure out why my side parking lights and backup lights have yet to turn on.

Seems to me that the turn signals, side parking lights and tail/brake lights should all be hooked together on the switch at a terminal where there is power to parking lights and headlights.

Wiring was definitely easier when the jeep was partially assembled.
