OEM sensor connectors for motorsport harness builds and sensor replacements. Every kit includes the housing, crimp terminals, and rubber seals — the complete mating connector assembly for the sensor already in your car or ready to wire into a new build.
The connectors stocked here cover the sensor families used across Bosch Motorsport, VAG, BMW, Honda, Toyota, and GM applications — the sensors that ECU builders, race car engineers, and engine swap builders encounter daily.
Bosch JPT Kompakt Series — Pressure & Position Sensors
Bosch’s official name for this family is Kompakt — you will also see them listed as “Compact” on reseller sites. Both names refer to the same connector. The JPT (Junior Power Timer) terminals are 2.8 mm. Two physical formats exist: Kompakt I (Code 1) with a side-entry locking tab, and Kompakt II (Code 2) with a top-entry tab. Housings look similar but are not interchangeable.
How to identify: narrow body with side-locking clip = EV1/Jetronic. Wide body with top-release button = USCAR. Honda/Toyota Sumitomo-style side-entry clip = Sumitomo kit.
The Trapez (trapezoidal) 5-pin housing fits Bosch combined manifold pressure and intake air temperature sensors used in VAG and other OEM applications.
What is the difference between JPT Code 1 and Code 2?
Code 1 (Kompakt I) and Code 2 (Kompakt II) use the same 2.8 mm JPT terminals but the locking tab is in a different position — Code 1 has a side-entry clip, Code 2 has a top-entry clip. The two codes are not interchangeable. Forcing the wrong housing will prevent it from locking and the connector can pull free under vibration. Check the tab direction on the sensor before ordering.
What connector does a Bosch LSU 4.9 wideband sensor use?
The Bosch LSU 4.9 uses a 6-pin round connector with 3.5 mm terminals. The LSU 4.9 connector kit includes housing, six crimp pins, and six seals. Pinout: Pin 1 = Pump current (IP), Pin 2 = Virtual ground (VM), Pin 3 = Heater−, Pin 4 = Heater+, Pin 5 = Cal resistor (IA), Pin 6 = Nernst cell voltage (UN). The LSU 4.2 uses a different 6-pin connector with a different pinout — the two are not interchangeable.
Which injector connector fits Bosch EV14 injectors?
Most Bosch EV14 injectors use the Jetronic/EV1 2-pin connector. However some high-flow EV14 variants — notably Bosch 0280158235 (731 cc/min @ 3 bar) — use the Sumitomo connector. Check the injector housing: a narrow body with a side-locking clip is EV1; a wider Sumitomo-style housing needs the Sumitomo kit.
Do these kits include everything needed, or do I need to buy terminals separately?
Every kit includes the complete set: connector housing, crimp terminals (female pins), and rubber seals. A crimp tool suitable for 2.8 mm JPT or 1.5 mm JMT terminals is required — not included. The kits are one-connector quantities; order multiple kits for multi-injector or multi-sensor installations.
