2-Pin 184020-1 1.8mm Female Connector – AMP Motorcycle & Automotive Signal Harness

Direct-fit replacement for TE Connectivity / AMP part number 184020-1, a 2-pin 1.8mm pitch female connector used in motorcycle and automotive signal harness applications. The 1.8mm series bridges the gap between the ultra-fine 1.2mm pitch and the more common 2.3mm pitch, providing a compact connector format for low-current signal circuits in space-constrained harness designs.

1.8mm Pitch – Handling Notes

The 1.8mm terminal pitch requires careful handling during crimping and installation:

• Strip length: 2.5–3.0mm – critical for correct terminal engagement without short circuits between adjacent pins
• Crimp tool: Use a precision ratchet crimper rated for 22 AWG (0.3 mm²) – Engineer PA-09 or equivalent. Standard automotive crimpers are too large.
• Terminal insertion: Insert straight and feel for the audible click of the terminal lock. Angled insertion will damage the housing cavity.

Frequently Asked Questions

Q: What is the mating male connector for 184020-1?
A: The mating male housing in the same AMP 1.8mm series is 184019-1 (2-pin male). Verify the male housing part number on your vehicle harness before ordering.

Q: Can I use 184020-1 for a brake light switch circuit?
A: Yes. Brake light switch circuits typically draw less than 1A (signal to ECU or relay). The 5A per pin rating of the 1.8mm series is more than sufficient for brake switch signal applications.

Q: Is this connector waterproof?
A: The 184020-1 is an unsealed connector – no rubber wire seals. For exposed locations subject to water spray (underbody brake switch, external sensors), use the sealed variant with individual wire seals.
