"Official CarQuery API WordPress Plugin" Embed

I am a Designer and not a coder and appreciate all the help.
I am useing the “Big Contact Plugin”but willing to use anything that will achieve what I want to do.

I have heard "Contact form 7" may be best.
Could some help me embed the “Official CarQuery API" short code into a "contact form 7" form.

I would like to replace the “Tell us about your car”
field with the “Official CarQuery API" short code, so someone can choose there make, model and year car and have that info sent with the message.

Could someone help me on the easiest way to do this ?


You guys and gals are the BEST !

Thanks JIM
