They go into directly into the PCM. the low reference signal also will connect to the HVAC system.

Okay that's why I couldn't find the other end. So it's not something I can unplug. You may know the answer to this.
I need to make my iat harness longer to relocate the sensor. They have extensions you can order but I can't get it here in time. If I solder the same size wire to the existing wire (maybe 2 extra feet) will it hurt the signal in anyway or mess anything up??
Thanks!

Not something you can unplug without having to remove the pins from the ECU. Soldering wire to the existing wire would actually conduct better than any extension plugging into it would so technically you're better off soldering it but either way neither of which would have enough effect to influence any of the signal going to and from the sensor, so go ahead and extend that cable

You should really do a mechanical splice if you are going to solder, particularly in an engine bay where the wires will be exposed to vibration. Pages 16-19 in GM's Terminal Repair guide show how to do this: http://www.weber.edu/wsuimages/autom...%20Booklet.pdf
In order to use any of these, you also need a really really good crimper.

(So, I just use the mechanical crimps now without solder, usually. I suppose one could also solder the wires first and then crimp later as a reinforcement.) LS1 Tech Stories
