Where do these wires go?

Yep came like that. Probably not too important. I haven't tried to fire it up yet but I don't see what it could really be for so I'll just leave it.

Anyone know what the wires are supposed to do? Will it run fine without them hooked up to anything?

I got a front clip, mine is unpluged. The way u see it in the pic, with wires cut off, I unpluged it when removed motor. If I remember correctly that has something to do with, HVAC. Think there was a sensor/probe in one of heating/coolant lines. My motor runs fine with out that. But if you like you should check the forum, look in FSM. But I'm not sure if the FSM work, I tried downloadig it couple of days ago, unless it's zip file. I started my car today, just regular monthly start , dont drive it in winter. Anyway I was like what da F@kz, what is that, but now I think I remember what it was for. Cauze I was looking at my fuel pressure regular, I got 2 one on front of rail and one on back wierd .GL.

Ah if it runs fine without it, I don't really care. Good to know. I'll just pull the plug out and leave it.

Thanks for the input guys.
