MegaSquirt Wiring Bundle – 23″ Long
Perfect for creating your harness adapter (perhaps using a DIYBOB along with this) or for tying into your stock wiring harness!
- 23″ TXL wire, color coded with labeling printed on the wire every 3 inches — no paper tags here!
- IAC and Ignition wires are included for MS-I or MS-2 use
- Shielded Ignition input wire
This will give you all of the color coded automotive grade wiring you’ll need to wire up all of the sensors, ignition components, and the ECU side of the injectors when tying into your factory wiring harness or building a harness adaptor.
