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\u003c\/p\u003e\n\u003cul\u003e\u003cli\u003eif you have any questions, please reach out to us.\u003c\/li\u003e\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003eEngine: S13\/S14\/S15 SR20DE\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAny RWD naturally aspirated SR20DE engine from S13, S14 or S15 chassis.
