Tachometric Relay Wiring Diagram. I am going straight gas and want to bypass the ecu. 2 as per sammys vk wiring mod diagram the injector white wire goes back to the tachometric relay however previous posts dont show this.
It shows the components of the circuit as simplified shapes and the facility and signal friends amongst the devices. I am going straight gas and want to bypass the ecu. 542020 1 connecting additional devices to the remote turn on wire 2 constant to momentary output negative inputnegative output 3 constant to momentary output negative inputpositive output 4 constant to momentary output positive inputnegative output 5.
As you can see there is absolutely no difference between the square type and the round type other than the ratings on the relay.
As i have a mechanical pump no need for the relay. This circuit should have 10 12 volts whenever the ignition is on. In the diagram i have wired the red wire to the tachometric relay from the ignition switch and put a fuse in line. Thanks for pointing that out cbus.
