Ignition On_Starter On Relay

[dave w]

I'm adding fuel injection to an old car, that had points. The challenge I'm working with is the old car had used the "R" terminal on the starter to power the points coil when the car was starting. The old car has an ignition switch that has either "Ignition On" power or "Starter On" power.

I'm wondering if anyone has successfully used a relay wired like the diagram pictured below to provide both "on & start" power to the fuel injection?

Basically terminals 30 & 87a are normally closed, so when the ignition switch is in the "start" position terminal 87a will send power to terminal 30.

Basically terminal 30 will get power from terminal 87 when the ignition switch is in the "Run or On" position.

Thoughts or alternative solutions are greatly appreciated
