YLCNC 1-1418390-1 4 PIN Ehicle Monitoring System Connector Automotive Wire Harness Junction Plug

The YLCNC-0750 is a 4-pin sealed PBT wire-to-wire automotive wire harness junction plug that cross-references OE NO. 1-1418390-1, so a worn automotive harness can be repaired by swapping this plug alone. Bulk pricing and sample quotes are both available once you send the YLCNC-0750 reference and your target quantity.

Product Advantages

1. Yellow-black junction body: The two-tone PBT housing makes the 4-pin junction instantly identifiable against plain black engine looms.

2. OE 1-1418390-1 match: Cavity spacing mirrors the factory part, letting the YLCNC-0750 plug mate onto existing automotive terminals.

3. Quad-seal waterproofing: Four wire seals trap moisture out of each contact pocket, even through high-pressure under-bonnet wash-down.

4. Junction-style consolidation: Four circuits meet at one wire-to-wire point, trimming the loose splices that fail on aftermarket looms.

5. Color-coded variant pick: The yellow-black shell lets assembly staff spot the 1-1418390-1 variant at a glance among plain black housings.

6. Bulk junction stocking: Repeat automotive customers draw the 4-way plug from stock, so line-side buffer kits stay replenished.

Main Application Scenarios

1. Under-bonnet relay junction boxes where the yellow-black 4-pin plug ties sensor feeds into one sealed point.

2. Aftermarket accessory fitters using the 1-1418390-1 style plug to splice fog-light and fan circuits cleanly.

3. Repair bays pulling a like-for-like 4-way junction when corrosion has greened the original plug contacts.

4. Harness builders routing four sensor circuits through a single color-identified YLCNC-0750 block.

5. Engine-assembly buffer kits that stock the yellow-black junction alongside common 2- and 3-way seals.

Service Advantages

1. Customized Services: Custom colours and shell shapes are prototyped fast, so the 4-pin part matches your brand or repair need. After-sales tool support is included, so a worn mould insert for the OE NO. 1-1418390-1 part is refreshed locally.

2. Standard Services: We level-load the automotive wire harness junction plug line, avoiding the shortages that plague automotive distributors during demand spikes. Bulk lead times are shortened by pre-cutting 4-pin leads to the gauge most automotive buyers request.

3. Value-added Services: Professional technical support is provided. We stand behind the sealed housing with warranty support, and document every correction made to the automotive wire harness junction plug.

FAQ

Q1: Does YLCNC-0750 substitute the factory OE NO. 1-1418390-1 housing exactly?

A1: Yes. YLCNC-0750 is a cross-reference replacement for OE NO. 1-1418390-1, with the original 4-pin cavity layout, yellow-black PBT shell and per-cavity seals for general automotive junction applications.

Q2: Which colors are stocked as standard for the YLCNC-0750?

A2: Colors are matched to your circuit list, and each automotive wire harness junction plug lead is taped neatly at the cable exit.

Q3: Are both genders priced the same for the 4-pin part?

A3: We supply pin contacts in the male and socket contacts in the female, already seated in the automotive wire harness junction plug.

Q4: How is a production lot of the automotive wire harness junction plug traceable?

A4: We run 270-plus staff across production, inspection and packing, each shift covering the sealed connector line.

Q5: Which price change comes from custom wire colors?

A5: Tooling fees apply only to truly custom variants, while a standard catalogue automotive wire harness junction plug ships with no setup charge.

Q6: Which compliance documents travel with a YLCNC-0750 bulk shipment to EU buyers?

A6: Each carton leaves with IATF16949, CE and RoHS declarations, so customs and your engineering file receive traceable paperwork.
