Our Pro-Series is ideal for those looking for the best aesthetics, weight savings and reliability. Completely replace your old harness and forget about electrical gremlins. Dress up your bay and take all the pain out of wiring work with this harness. This harness is specifically engineered for any Datsun with a SR20DE engine swap. It was developed in house on an actual SR20DE engine to ensure a perfect fit to all engine connections. Our PRO harnesses are a perfect solution for the engine, and can come with an optional self-contained pre-wired fuse/relay block for ignition, cooling fans and fuel pump. If you plan on using your own relays and a switch panel, you do not need the fuse block. You just have to hook up start signal, fuel pump wires and a few other wires for tach and speedo, alternator warning light etc. Speedo and / or tach may need to have the signal adjusted using a frequency modulator (see Options to the right). You may have to run aftermarket gauges. Not compatible with mechanical cable driven speedometers. Wiring Specialties offers a number of options for common performance upgrades for this product. Build your perfect harness by selecting from the available options, and as always

- NOTE: The S13, S14 and S15 SR20DEs do differ in ECU and engine wiring. The actual harness will be finished to the specifications selected in the order
- When using the S13/S14 SR transmissions, the speed sensor from these transmissions will be wired in and will allow the speedometer to function
- The S15 SR20DE 5-speed Transmission does NOT have a speed sensor and the speedometer will not function. A S15 differential should be used to generate a speed sensor signal. This option must include the SGI5 frequency modulator to allow for calibrating the speed signal and accurately display the speed
- **For aftermarket ECUs and Speed/Density conversion, the harness will include an IAT sensor and a MAP sensor connectors instead of the MAFS connectors
- ** Most aftermarket ECUs will require conversion to coil on plug ignition system.
