MegaSquirt Wiring Bundle

• 12' 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

Great for building up your own wiring harness, or wiring up your relay board where this will give you all of the color coded automotive grade wiring you'll need to wire up the ECU side of the sensors (plus a single 14 ga wire for sensor grounds), ignition components, and the ECU side of the injectors. For building your own harness on a previously EFI'd car you're good to go, for wiring up a relay board you'll just need the fuel pump wire, 12v supply wire to the injectors and maybe a bit of wire to connect the IAT/CLT sensors to the 14ga sensor ground wire and you're good to go.
