Painless

I just ordered my Painless wiring harness (plug and play version). I’ve been waiting for this day for 4 years! I just had to tell someone. Up for any advice or YouTube links.

I did mine a number of years ago and it was truly painless. Every single wire was marked on the wire where it goes. You can expect something like that to be color coded but it's printed on the wire left turn or right turn or whatever it is used for. You don't have to go back to the instructions over and over to find out where the tan wire with the white stripe goes.

Do not cut them! route them, do some other work check the routing again. Save the final cutting and terminating for last.
Otherwise you will end up cutting something too short that shouldn't be:-)

Just finished rewiring my 81 cj5 with the painless plug and play last night. Love it. I agree do not cut until end and test everything. Was just relieved it started up on 1st try.

Also keep in mind your add on items that may not be routed in a clean logical way. If you wire up and terminate you wont be able to undo it in a reasonable manner. I added an electric vacuum pump, nitrous solenoids and electronic speedometer and Tach after I had the main bundle pushed through the firewall with taping and wireloom and proceeded to terminate the ends. When I went back later to add the additional items I had to run another penetration through the firewall :-(

Extremely happy with the Painless wiring harness. I just hope I’m doing a good job. If I’m making a mistake, I’d guess it’s probably leaving excess wire that I’ll need to coil up and cover with the black wire shell material. I’ve added some pics below as I’m mid-job. It took me approximately 7 hours to pull old harness, unpack new harness, and install dash and engine portion (minus the Duraspark ignition items).

So learning as I go, I figured out I have the Duraspark II Ignition System. I’ll be ordering that and, while I’m at it, a new temperature sensor on the intake manifold and ignition module. I hate to do all the work and not finish the few extra things that will give the future reliability I’m looking for.

If there are any questions and comments I’d throw out there, it would be:

(1) Why is the MIDI fuse necessary if I didn’t have that on my rig before?
(2) Why didn’t they include the hood light while they were at it? Still looking for this.
(3) Why doesn’t the Duraspark Ignition System addition come with the ignition module?
(4) I’m realizing now that all the extra cut cord that didn’t go anywhere and scared me was more than likely factory options that I didn’t have.
(5) I wish I would have bought quality crimpers.
(6) I used screw and plastic but set for installing a license plate set to mount headlights as those fittings were worn and at end of life.

Anyway, hope these comments are helpful to the next guy.

I put off buying one until I got the old wiring harness out and saw the damage a few previous owners had done to it and decided that spending the 800 dollar was preferable to trying to build my own harness...........and I was right. Some of the best money I spent on my CJ5 rebuild.

So not sure if this is common but I’m at the finish line installing the Duraspark II extra harness and the wires aren’t long enough to go properly to the firewall (in an up and around kind of way) and around the coil and things. Certainly the solenoid wires are way short no matter what path you take.

Is it ok to send the wires in the plastic corrugated wire loom wrap over the valve cover?

For the Duraspark II ignition harness, do they include a ballast resistor to the ignition coil?
You will need one unless Painless started adding resistance wire going to the coil.

If they did not, then you can mount the ballast resistor to the firewall and run the proper length wire to reach the coil.

How did they run the bypass wire to the solenoid terminal "I"

Thanks John. They include one for both the harness kit and the Duraspark kit. I mounted it on the ignition coil mounting bolt which seemed easy, dry, and convenient. The brown and white wires from the Duraspark harness are pre-routed from the Duraspark module to the other side as open wires. Just not long enough. I believe I will cut wires from my old harness and extend almost all wires with same color wiring and keep it all against the fire wall in the plastic sheathing.

Excited!! Well, she started right up. Oil and battery gauge lit up and worked perfect.

The only disappointment is that my rear marker lights do not blink alternately as they used to with my brake lights. The rear brake lights blink but not my rear marker lights! The front marker lights blink alternately with the front but just not in the rear.

I recommend this kit. Glad to know my old CJ is less likely to cause a fire. Glad to have knowledge of the wires and what isn’t connected.

I know that in my 76, the rear red marker lights were never designed to blink with turn signals...only the front amber marker lights alternated with the parking lights up front for the turn signal. I'd be surprised if they changed that for your year, so I'd guess that a PO wired it differently...either intentionally or unintentionally.

Either way, that harness is designed to work like that, so you didn't do anything wrong.

I used the same Painless kit last summer when I did my 351w swap. Definitely well worth the money. I was easily able to hook up my Sniper EFI with all the Hyperspark goodies, dual electric fans, electric fuel pump, Speedhut gauges and USB/12V charging sockets.

Awesome. That is great to hear! Now I really have no complaints. Thanks for sharing.
