MPGuino install in a '91 Mustang?

Would this be the same process as installing it in a civic? Just find the VSS signal, injector signal at the ECU then using a 12v power from somewhere in the fuse box? I really don't want to go through the firewall into the engine compartment.

I found this diagram but, I'm not to sure which injector to go after? I see the VSS signal so I'll just tap into that, but which injector should I use?

Installation notes:
For Identifying where to tap into the fuel injector:
1. turn on the ignition, leave engine off.
2. Unplug an injector.
3. With a voltmeter, measure the voltage on each injector connection. One should be 12 volts and the other should be more like 0.
You will want to tap into the one that is at 0 volts.

But it shouldn't matter which injector.
