I need to replace the wiring pigtail on my 2014 model 171. Can I use one that doesn't require wire splicing. How do I remove the old one. Etrailer has a plug in one that is for Forest River. Appreciate any help you can give me.

Welcome to the forum. Most of the 7-Pin connectors are spliced to the trailer wiring on or near the trailer A-frame from the factory. There are kits I've seen that provide a screw type buss bar to wire both sides to in a waterproof box. The advantage is everything is screwed together with no splicing, but they can vibrate loose.

Can you post a link to what you're looking at on etrailer?

X2 on providing a link. Sounds like you're talking about an extension. If you need to replace it because of damage or connection issues, it's pretty much going to need some sort of connections, whether splice or terminals.

I'd get one of these new pigtails:

There should be a junction box under your A-frame near the front of the trailer. Remove the cover and you'll see that the old pigtail is connected to the trailer wiring with wire nuts or crimp connectors. Remove each old wire one at a time and replace with the new wire using wire nuts or splices.

That's what I would do.

If your problem is only the 7-pin connector at the end, you can buy just the connector, like on the left in this pic:

Then you'd cut off the old one, strip back the outer insulation of the pigtail to get enough of the wiring loose, then strip the insulation off each wire and screw it to the appropriate screw on the new connector. This method won't be sealed as well at the connector as a new pigtail will be.

When you get around to doing this, please double check the wiring. Do not assume that everyone uses the same color code for wiring.

On my A122S A frame, about 4 feet back from the 7 pin RV plug is a 6 pin connector. See photo. You may be able to buy such a cord.

Never replaced one that didn't require some sort of splicing, if not comfortable with that take it somewhere that can assist. The Pods I have worked on were wired to the RV standard 7 pin. Not a trailer 7 pin or anything but a RV standard, the wiring colors matched. Your spliced connectors are on the left side front behind the A frame.
