  • $25

ECU header used in FC and FD RX-7.  The FC version is a 3 connector version and does not have the 16 pin connector in the middle but the other 3 connectors are identical.  We use these headers to produce our plug-in harnesses for easy connection to the front harness with no splices required.  AC control, speedo output, and more can be connected through this header.
