Fuel Pump Wiring Alternative

[fishdad]

Hi all,

New to the forum and to jeep with a 2006 KJ 3.7L V6 2WD. I bought it for cheap knowing it needed some work and had a check engine light for a u1411 code. I confirmed that gauges work by holding the odometer button, and replaced all the parts that needed it. I started to tackle the u1411 code by replacing the fuel pump, ignition switch, and checking the fuses. None of these fixed the issue, even after clearing the code.

However, while I was replacing the pump, I saw that the wiring connecting to the fuel pump looked pretty janky like the previous owner had spliced it before, pics attached below.

My questions are:
1. could damaged wires give the u1411 code?
2. what fuel pump wiring harnesses are compatible with a 2006 KJ?
On mopar, it's listed as part number 56047848AB, but it's discontinued and I can only find the connector with the wires cut on ebay.

I'd want to replace that whole segment vs splicing it again, and any advice is appreciated!

Consider shopping that part number at a Napa Auto Parts near you. They can likely match a connector and pins in their Belkin line of auto electrical. I got some great OEM style plugs for some GM applications that I could not source at a reasonable price. Napa had it overnite, good pricing too. You would need the connector and pins. Maybe a bit of wire and solder those connections. Crimps are not likely to hold up as well.

I'll check it out! I want to avoid soldering if I can, but I'll learn if I have to.
