I havae a weird problem. While I was changing out my starter, I noticed a large plug on the passenger side that was unplugged. So naturally, I plugged it back in. After restarting my car I noticed it ran very, very rough. But I also noticed that my ABS and "Brake" light were no longer on.

So I shut off the car and unplugged the plug I found, restarted the car. Car ran fine but the ABS and "Brake" light were back on. What in the hell is going on with my car. How would a break system piece screw up my engine?

it is under the washer reservoir, and under the battery, it might be the ebcm, but still

That is the EBCM, that is if you are talking about the drivers side. It is a rather large plug, but I'm not sure why it would cause the car to run rough.

The EBCM is only really accessible if you pull the inner fender liner, in front of the wheel.
it is rectangular with a screw in the center that holds it tight to the abs computer. If that is the one it definitely tells why the abs and brake light are on. No communication to the pcm and other computers.
As to why it would cause the engine to run rough that might be a faulty ground in the wire harness that causes the pcm to try to compensate?

yeah driver's side I was under car so got turned around, but yeah it is really weird. How can I check to see if it is a bad ground?

Something to add, the ebcm makes a rythmic ticking noise when plugged in, and there is a ticking from what sounds like a fuel injector. Not sure if it is an FI, but it is coming fromthat area.
