Frequently Asked Questions
Q: Which VW/Audi models use the 357972771 connector?
The 357972771 is used across a wide range of VAG vehicles including VW Golf Mk3/Mk4, Passat B4/B5, Polo 6N/9N, Jetta Mk3/Mk4, Audi A4 B5/B6, A3 8L/8P, and many other VAG-platform vehicles from the mid-1990s through mid-2000s. Cross-reference the part number on your existing connector or consult your vehicle’s wiring diagram to confirm.
Q: Is this the same as the Tyco/AMP 6.3mm connector?
The VAG 357972771 uses a 6.3mm terminal pitch compatible with the Tyco/AMP 6.3mm series. However, housing dimensions and locking tab geometry may differ between VAG OEM and generic 6.3mm connectors. For guaranteed fitment, use the OEM part number reference.
Q: What crimping tool do I need?
Use a ratchet-type automotive crimping tool with a jaw sized for 6.3mm open-barrel terminals. The terminal has separate wire barrel and insulation barrel sections. Crimp the wire barrel first for electrical contact, then crimp the insulation barrel for strain relief. A proper crimp withstands a minimum 30N pull-out force.
