Rywire SR20DET Swap Mil-Spec Engine Harness - Nissan S13 SR20DET (S13-Milspec)

Rywire S13-Milspec is a mil-spec engine harness for the S13 SR20DET, whether it lives in a Nissan or goes into a non-Nissan car as an SR20 swap. The lower transmission harness is built in, so it is one harness instead of two, and the MAF connector is a Deutsch plug, making it easy to move to an aftermarket MAF or a standalone MAP/IAT setup. Each harness comes with a chassis adapter for the car you choose: change chassis later and you only need a new adapter.

Frequently Asked Questions

Can I use it in a non-Nissan car?

Yes. It is designed for an S13 SR20DET in a Nissan or a non-Nissan car. Choose Race / Flying Lead if your chassis does not match one of the listed years.

Which computer does it plug into?

It is built with 1991-1999 180SX computer connectors, so it plugs into the 180SX computer, the AEM EMS 30-6601 and plug-and-play standalones such as Haltech. Ask us about other computer configurations.

Are the coils on this harness?

No. The harness connects to the factory coil sub-harness through a 6-pin connector; coil harnesses are available for an added fee. Email service@tunedbyshawn.com with your engine, chassis and ECU before ordering if you are unsure which configuration you need. Tuned By Shawn can tune your swap on Haltech.
