Regular price $99.00 Sale

  • Custom made twisted pair cable with a foil shield for ignition input, for maximum noise suppression.
  • Thumbscrews make it easier to tighten down in spots where you can’t easily fit a screwdriver.
  • Wires for pins 3 through 6 have been added for CANBUS or extra I/O.
  • Injector wires use two smaller wires instead of combining two pins into one large wire, reducing the number of splices needed in your harness.
  • Wires are printed with both their function and their pin number.
  • Dedicated sensor ground wire.
  • IAC and Ignition wire have been added for MS-I / MS-2 use or MS-3 Primary Harness Use
  • 8′ of TXL High temp automotive grade wire.
  • Color coded wiring with labeling printed on the wire every 5 inches — no paper tags here!
  • All wiring is pre-crimped (NOT solder cupped!) to the DB37
  • Heavy duty metal DB37 hood for superior RFI/EMI shielding (no cheap plastic ‘metalized’ hoods used on our harnesses)
  • Wiring diagram included
  • Simply the best MegaSquirt harness available anywhere, at any price

Note: The Wiring Harness and Relay Cable are ‘mutually exclusive’, meaning they are not designed to be used together. If you are using the wiring harness then you are wiring everything directly back to the DB37 on the ECU with relays and fuses where needed. If you are using the Relay Cable you are connecting the DB37 on the ECU to the Relay Board directly (so there is nowhere to plug the harness in anymore) and you then wire everything directly to the screw terminals on the relay board. Our Wiring Bundle comes in handy for installation with a Relay Board.
