MegaSquirt Wiring Harness – 24 inches long

Completely redesigned version adds more features to help make your installation as easy and reliable as possible. We’ve now brought the improvements from the long harness over to the pigtail harness. This mini-harness is useful for wiring up a DIYBOB adapter board, creating homemade adapter harnesses, or cutting off the connector on an OEM harness and splicing this in.

  • We now use a custom made twisted pair cable with a foil shield for ignition input, for maximum noise supression.
  • Thumbscrews make it easier to tighten down in spots where you can’t easily put a screwdriver.
  • The wires for pins 3 through 6 have been added, for CANBUS or extra I/O.
  • Choice of 24″ or 10′ lengths
  • The injector wires now 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.

And, of course, we’ve kept the features you’d expect from one of our wiring harnesses:

  • IAC and Ignition wire have been added for MS-I/MS-2 use or MS-3 Primary Harness Use
  • 12′ 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)
  • Simply the best MegaSquirt harness available anywhere, at any price

1 review for 24″ MegaSquirt Pigtail Harness (MS1/MS2/MS3 Ready)

  1. 5 out of 5

    Working well for Traction Control and VSS. Going to try for Crank signal now.I have 2 of these already on the vehicle. One at the rear end pinion for VSS1 running on a 4 magnet wheel and one on the front hub reading the heads of the lug studs (6 lugs). Both are working well. I am going to try one on the front of the crank with a 36-1 wheel. I bought 2, one to keep as a spare, since I now have 3 on the vehicle.

    Well made, machines easily.Picture is very accurate. It machines easily and is well made. Should be a good improvement over my 8 window stock trigger.

    Hall Effect Crankshaft Position SensorI bought this item, it's not dirt cheap to me. But, I purchased it. Using it with ms2 extra. Had to do few steps, solder few wires to make it work. Instructions online available step by step. It was easy enough and the felling was rewarding that I did it. The sensor works beautifully, it does the job very nicely, so far I have no complains. Would say much sharper than the pickup sensor for sure. (Project: rotary engine Rx7) thanks diyautotune.
