4-Pin 1-967640-1 / 2-967640-1 Tyco AMP 0.6mm Waterproof Connector – BMW Signal Harness

Direct-fit replacement for Tyco Electronics (now TE Connectivity) / AMP part numbers 1-967640-1 (male plug) and 2-967640-1 (female socket), a 4-pin waterproof 0.6mm pitch connector used for ECU and sensor signal harness connections on BMW vehicles. The 0.6mm pitch provides ultra-compact IP68-sealed connections for low-current signal circuits in BMW engine management and body control harnesses.

Tyco vs AMP – Same Connector?

Yes. Tyco Electronics acquired AMP in 1999 and was subsequently renamed TE Connectivity in 2011. Part numbers prefixed with 1-XXXXXX-X or 2-XXXXXX-X are TE Connectivity / AMP / Tyco parts – all the same manufacturer. The 1-967640-1 and 2-967640-1 are current production parts available under the TE Connectivity brand.

Compatible BMW Applications

• BMW 3 Series (E46/E90/E92): ECU signal harness and sensor connectors
• BMW 5 Series (E39/E60): Engine management signal wiring
• BMW X5 (E53/E70): Body control module (BCM) signal harness
• BMW 1 Series (E87/E81): Instrument cluster and sensor signal connectors

0.6mm Pitch – Critical Handling

• Precision crimping mandatory: Use micro-crimper rated for 0.3mm² – Engineer PA-09 or TE 91516-1
• Strip length: 2.5–3.0mm exactly – too long risks inter-pin shorts at 0.6mm spacing
• ESD protection: Use wrist strap when handling ECU circuit connectors
• Wire seal: 22 AWG wire mandatory – larger gauge compromises IP68 rating

Frequently Asked Questions

Q: Are 1-967640-1 and 2-967640-1 a matched pair?
A: Yes. 1-967640-1 is the male plug; 2-967640-1 is the female socket. The prefix digit (1 vs 2) denotes male vs female in this TE Connectivity series.

Q: What diagnostic tool is needed for BMW fault codes?
A: Use BMW ISTA+ or a compatible scanner with BMW-specific protocols (INPA, Carly, or equivalent). Standard OBD2 scanners may not access all BMW-specific modules.
