History

• This old style Level 1 harness was made to splice another ECU into an existing Spitronics Harness. Firmware like the RPM Converters required only the RPM signal. This was done where the existing ECU cannot simulate the OEM crank and cam sensor patters to keep the OEM ECU alive.

Design Points to take Notice of.

• It has only the Crank RPM signal. Both ECU earths must be tied on the same earth point. These wires are not shielded and should be close to the other ECU.

Wire Names and connections on this harness:

RPM Input Signal (Green)

+12V Ignition (Red)

Earth (Black)

See the design drawing for thickness and lengths or wires. See the connection drawings in the specific product manual on how to connect the harness to each item it was designed for.

NB! Wires that are not connected must be isolated to prevent shorts or interference.
