No Splice Tow Bar Lighting Recommendation for 2025 Jeep Wrangler Sport  

Updated 02/02/2026 | Published 01/26/2026

Question:

Which wiring kit would I need to install on a flat tow jeep? It’s a 2025 jeep wrangler sport s. And is there a kit that does not have to splice in and has the plugs? It would go to a 6 pin plug in the front. Thank you

Hey Tracy, for a no-splice tow bar lighting solution for your 2025 Jeep Wrangler you'd want the Blue Ox part # BLU79FR. This doesn't have a 6-way on it though so you would need an adapter to go from the 4-way to it like with the part # RM59DQ and it would plug right into your 6-way. Sometimes people think a 7-way is a 6-way so if that adapter doesn't look right it might be that you need the part # TS42SR instead.

Ok I was also reading where there is a brake relay that has to be installed also. Is this true? Or does this system you send eliminate that? I noticed I can’t find a video on it for 2025 with push button start

@TracyB Most likely you do need a brake lite relay part # RM-88400 but you can test this pretty easily by checking a couple things. With the key off does your brake lights light up when you press the brake pedal? If so, then yes you would need it. We have had to install them on similar Wranglers like what's in the attached video.

@JamesonC do you have a video on gay includes the blue wire. All the videos I have seen on the site are not for push button starts. I believe that blue wire is for that.

@Tracy could I get you to rephrase your first question? I am not sure what you are asking?
