I just don't know what these two extra wires are for. I hope they go to something to add MORE POWER.

I haven't seen my truck in almost 6 months, so I am a little rusty about what things are called. lol.
I can't see it being the air temp- in fact i know it isn't that. I will have to look up the instructions from Edge, and let you know.

I hear people talking on here about tapping wires what's this all about? What would I gain by doing this, Hopefully more power. If more power is the case where do I do the cutting at? I have a Van Aaken installed on my truck now. It's an old chip but still works great.
