Frequently Asked Questions:

Q: Can i use a OBD2 USDM ECU with this?

A: No. Not unless you use a Obd1-2 USDM jumper haness with secondary 02 pigtail. For an added fee we can install Obd2 plugs for JDM computers, or AEM standalone systems.

Q: Is there VTEC pressure switch wiring on the mil-spec standalone harness?

A: No, there is not, we decided it would be best to simply bypass that sensor all together, no code will be thrown with the use of our harness. You can simply remove the sensor and replace it with a Honda OEM bolt.


Q: Is there Power steering or AC wiring on the Rywire Mil-spec standalone wire harness?

A: No, there is not. This is a standalone wire harness we do not add those accessories. Adding AC or power steering  is not a difficult   thing to add however.
