Where is this harness manufactured?

  • It is assembled in the USA.

What sort of serial cable does it use?

  • It uses the same DB9 to 2.5 mm barrel connector used with the Innovate LC-1 and VVTuner.

What grade of wiring is used?

  • This harness uses 20 gauge TXL high temperature automotive wiring. All wires are color coded and printed with their functions.

Where can I get a wiring diagram for it?

Can I remove any wires I’m not using?

  • Yes. You can unlock the connector with a screwdriver, at which point unused wires simply pull out the back of the connector. If you need to maintain waterproofing, you will need to insert a cavity plug into the connector (not included).

    Yes - the main difference is the VR2 wiring is a little different. On a V3 MicroSquirt, the VR2 wire is a differential input; on the earlier ones, it's a sensor ground.
