HARLEY FL FX SPORTSTER HEADLIGHT CONNECTOR PLUG 3 post CHOPPER BUILD

That's very close to my fathers 247.288841. He recently caught it on fire mulching leaves. I could not find a wiring diagram in any of the manuals online.

I bought a new wiring harness to replace the one he melted. The harness was only about $50 and it was easier than trying to repair the melted wires. The wiring harness was amazingly complete. It included EVERYTHING from the battery bolts all the way to the front headlight sockets. It came with all the plastic retainers that fasten it to the frame.

It's possible I could answer specific questions, but I have no diagram.

You need to get yourself a shop manual and rewire the harness in accordance with the wiring diagram in that manual. I bet if you look online you can download it for free like I did.

It's the rear wiring harness, and more specifically, the taillight harness.
Are there any wires left? Could you splice in new wires using solder on the connections, and heat shrink tubing? (Plus wiring wrap)

Wire the new one up, and where to get it?

Instead of buying a manual that may not be detailed enough, (Chiltons, and so on. You need a Shop Manual), I suggest you go down to your nearest Dodge dealer> Parts Department, and see if the Ol' Boys will copy off this part of the wiring diagram you need.
Shouldn't be but a few bucks.

They should have the wiring harness you need also.

OR,
you could buy the length of wires you need, match the color code of the insulation on the various wires, and the gauge of the wires, (Thickness of the wire), reuse the rubber connecting plugs, and other connectors, and wrap this wiring harness you made in electrical tape.

Naturally you won't reuse a melted rubber plug, (or Socket), and you'll have to buy any metal terminal ends you need.
That flexible plastic cover you see over the old wiring harness, is sold also. (Use electrical tape, and this flexible cover)

Wiring diagram? Here are the Wiring Schematics,

You have to become a member. It's free. Go up to the top right, and click on -> Become A Member.

Now on the main page you started from, go to the left side, and click on -> Vehicle Repair Guides.
On the next page go up to the top left, and click on the blue -> Manage My Vehicles
Now go to the right, and click on -> Add A Vehicle, in the orange box.

This takes to several pages. First page you choose the Year. Second page you choose the
Make. Third page you choose the Model. (I chose RAM 1500 1/2 Ton 2WD) Fourth page you choose the Engine. (We're after the wiring schematics for the rear of the truck, so I just picked one)

NOW, (Finally, lol!), under the Select A Category heading, click on Vehicle Repair Guides.
Go to the right, and click on -> Chassis Electrical
Now under the Select A Chapter heading, go down to the bottom, and click on -> Wiring Diagrams.

Fig. 27 is the wiring diagram you want. I would also look at the first two diagrams to familiarize yourself with reading wiring schematics, unless you are already adept at this.

Would appreciate it if you would rate my solution.

Headlight switches tend to over heat and melt wiring harness replace switch and harness should help with this problem if you can extend the harness will help in the future.
