LS Computer outputs - tied high, floating, what?

[davepl]

I'm a software guy, not a hardware guy, so... on LS engine controllers (like the E67 for the LS3) does anyone know if an output, like the fan relay controls, are left to float or are they tied high when not active?

I want to add some LEDs to show what the computer is asking for, but don't know if the outputs are +12V or floating or what they do when they're not "ON" (tied to ground).

If I had one handy, I'd go measure it, but nothing actively running right now.
