EFI and Ignition Switch

[vertex]

When you hook the EFI harness to the ignition switch do you want to run the wire to the "run" lead or the "start" lead or both. I know that you want the sensors to have power in the start position and the run position.

Do the wires that are hooked to the "run" lead also have power in the "start" position?

Is there a different lead I can tap into in order to get my switchable power?

I have a similar question. I just hooked mine up and thought I was smart by running the wires that are labeled (Crank/Run) to both, however, this jumped the starter because when I would just turn it to run it would give power to the start postion and engage the starter. So, I took those wire off start and just ran the crank/run wires to run only. It seems to work great though. I'll let you know if I run into anything.

Thanks

I was supposed to work on the wiring this weekend but stuff came up. This weekend I am going to finish up the wiring and try testing the harness.

I can't start it because I don't have my new gas tank and I don't have a fuel pump yet but I will test all the wiring so all I have to do is give it some fuel and hopefully it will start.

I just figured this out, wires in Run do get power in Start as well. My bronco is running very well (just dialed it in tonight) and I just wired all crank/run to run. Have fun!

Thanks for the info I will wire it to the run position of the switch.
