Description
MegaSquirt Wiring Harness – 8 Feet Long
We’ve completely redesigned our wire harness to help you get your fuel injection installation right the first time with several new features to help make your installation as easy and reliable as possible:
- We use a 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.
- Your choice of 2′ or 10′ lengths (see MSPiggy short harness)
- 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.
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
- 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
Product FAQ
What sort of wire do you use in this harness?
- We use 20 gauge high temperature, automotive grade TXL wire.
Are all the pins populated?
- We populate all the pins except for some of the ground pins. The main board does not require using all the grounds. See our MegaSquirt grounding page for more information.
If I am using an MS3 with MS3X, do I use this harness or the MS3X harness?
- The MS3 with MS3X has two DB37 connectors, each of which use a harness. This harness connects to the lower (main board) connector, while the upper (MS3X) connector uses the MS3X harness.
Where is this harness made?
- We assemble this harness in Gainesville, Georgia, USA.
