yes, I saw the install link. I wasnt questioning the installation procedures, rather I was questioning the proper model unit to order depending on the given situation of which H2 one has.

 

You got it right. Let me know how you like it.

 

where is the heater on the 2007 h2 located and if you had the uninstall done at dealer do you need any other parts or fuses to replace it with the alpha unit or do they give you everything

 

IIRC The heater is on the passenger side firewall, there might be a fuse you need as the dealer was supposed to remove the fuse when they did the uninstall but my dealer left my fuse on there.

 

Is there anywhere that has a picture of it on the h2 and does the company that makes it sell the fuse also do you know i looked on mine and it must be behind the air induct because i cannot see it at all but bottle is there

 

Here's the location of the oem w/w heater (No.1 on the diagram).

AIR INTAKE SYSTEM. Fits: Hummer H2 | Nalley Buick GMC Brunswick

I installed this 2 years ago, really liked it especially in freezing temperatures and no additional switch required. I will also install this on my wifes H3 soon. I bought the oem bracket for a nice clean install.
