Product Description

MegaSquirt MS3X Wiring Pigtail – Length = 24″

  • 24″ of TXL High temp automotive grade wire.
  • Color coded wiring with labeling printed on the wire every 6 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)
  • Use with MS3X Expansion board

This is a shorter version of the harness for the MS3X Expansion board. We’ve custom printed these to include all the inputs and outputs on the expansion board. Note that you will still need our regular MSPiggy for the main board DB37 – this is just the MS3X harness. Includes wiring for sequential injection, sequential coil on plug, nitrous, boost control, and more. Perfect for splicing into stock wiring or connecting to a DIYBOB for home brew plug and play systems.
