Hey guys, I ordered a Ver 2 kit, and I've got some things I'm concerned about... I have a 93 Saturn SL2 (Auto) and I have a Haynes Manual which is where I'm looking at the wiring diagrams to figure out where I'm going to tap in my wires.

It looks like I have a VSS Hi and VSS Lo wire. Also, there are wires for each individual fuel injector..

Which wires will I use? The 12 V and the ground are a no brainer, but the VSS hi and VSS lo, and does it matter which injector I tap into? Those are my concerns, these are all wires going into the PCM. Is that the same as the ECU that I've read about? I'm assuming it is, but I just thought I'd ask.

I've only seen a 1997 Saturn as far as reference numbers for hooking up the MPGuino, so if anyone has any tips for me I would REALLY appreciate it. Thanks!
