Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

Compact EOBD Port Expander Y Lead for P3 V3 Gauge

Turn one 16-pin diagnostic socket into two with this slimline, flat-harness Y lead. Built for tidy installs behind trim and under the dashboard, it lets you run a P3 V3 gauge while keeping your vehicle’s data link connector free for fault code readers, scan tools and other onboard diagnostics equipment. Clean look, reliable connection, zero hassle.

Why enthusiasts choose it

  • Create a twin-port diagnostic interface from a single DLC for maximum flexibility
  • Ultra-low profile, thin and flat cable for discreet routing and an OEM-style finish
  • Seamless with P3 V3 gauge setups while preserving access for servicing and diagnostics
  • Tool-free install - simply plug in and route for a stealth, factory-style appearance
  • Maintains solid communication for multiple devices with a minimal footprint
  • Exact style may vary

Real-world use

We run this splitter in our own builds and customer cars, and it has been consistently dependable. Owners love keeping their gauge live without sacrificing access for health checks, code scanning or tuning workflows. It just works, and it looks neat while doing it.

Compatibility

  • Designed for use with the P3 V3 gauge
  • Fits standard 16-pin EOBD - OBD diagnostic sockets

Good to know

Not every connected device can operate at the same time on the same vehicle. In some setups, setting P3Gauges to analogue mode or low priority mode allows shared use with other equipment. Results vary by vehicle and device.
