EFI Swap Done - Can not find Start/Run Lead for to power ECU

[BFD305]

The swap is done, and we are driving the bronco, but right now I am powering the ignition to the computer with a toggle. I can not find a wire anywhere that is hot in both run and start positions.

I am running a stock ignition switch and main harness in a 1976 Bronco, and then a factory ford harness from the grand marquis.

Is a double solenoid setup the only way? Seems like there has to be a lead that is Off in the Off position and Hot in the run and start, but we are not finding it.

I have searched the forums and I do not have the double green one member talked about.

Any ideas? Thanks

Wire 904, Green with Red stripe coming from the ignition switch, should be hot in Run and Start.

It only takes 1 dedicated relay for EEC PWR, but you might need to change your starter relay to one with an "I" output. Run a wire from the ig.sw. that's hot in RUN to the EEC PWR relay's trigger, and then to the I terminal of the starter relay. Run the EEC PWR relay's other trigger to ground. That way, when it's not getting 12V directly from the ig.sw., it'll get it from the starter relay. But nothing will be cross-connected at any time.
