Get the 30-0300, it comes with the complete harness. The 30-0333 is for new cars that can read the sensor off the canbus. Get the 30-0300. **Q: Why does it show pictures of the 30-0311 but states this product is the 30-0344 for “piggy back” capabilities with hp tuners?** A: Not entirely sure what you mean. My kit came as pictured and works as advertised. **Q: Will this wideband gauge work in “standalone mode”? i have a carbureted vehicle i need to tune and have no use for the obdii connectivity.** A: Yes. The gauge will display AFR on its own without connecting any of the obdii wiring **Q: Does the digital gauge still work if the obd port is not connected? I would use this wideband for multiple car use not a single install.** A: Yes. The OBD pass through connector is just to get the information into your data logging software. The sensor reads into the gauge and then sends signal through a separate plug to the OBD port. ## Frequently Bought Together - AEM X-Series Wideband UEGO AFR Sensor Controller Gauge with OBDII Connectivity - HP Tuners PROLINK+ Cable with Analog and CAN Bus inputs for External Sensors Using MPVI2+ and MPVI3 OBD2 Scan Tools, Cable Only - GlowShift Universal Black Single Gauge Swivel Dashboard Pod - Fits Any Make/Model - Swivels 360 Degrees - ABS Plastic - Mounts (1) 2-1/16" (52mm) Gauge to Vehicle's Dash --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/289509011-aem-30-0333-x-series-obdii-wideband-uego-afr-sensor](https://www.desertcart.jp/products/289509011-aem-30-0333-x-series-obdii-wideband-uego-afr-sensor) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-22*
