Classic Performance: Bosch EV1 / Junior Timer Connector Kit
The Bosch EV1 (Jetronic) connector is an icon of the performance world, utilized on everything from the Toyota 2JZ-GTE and Nissan RB26DETT to 5.0L Ford Mustangs and European classics. Known as the “Junior Timer” (JPT) connector, this rectangular 2-pin plug is the standard for older high-impedance and low-impedance injectors, as well as many temperature sensors, idle control valves, and knock sensors. This Plug and Pins Only Kit provides the components necessary to repair aged, brittle factory connectors or build a new harness for these legacy applications.
Restoration and Repair
Over decades of heat cycling, the original plastic EV1 connectors often crack, and the spring tension in the terminals fades, leading to misfires or sensor dropouts. This kit features high-quality replacement housings with the distinctive metal spring-clip release mechanism (or internal latch depending on sub-revision) and fresh terminals. These terminals allow for a fresh crimp onto clean copper wire, restoring the electrical integrity of the circuit. This is essential for maintaining proper injector firing events and accurate sensor data in older vehicles.
