Adding a HUD

Hey everyone,

I have a 2002 GP GT and i want to add the pontiac HUD, i know i can buy the panel, switch and projector from ebay, but does anyone know how to install it.

Ive tried google and other search engines and keep finding dead links and car reviews(i dont know why)....

any help is very much appreciated
thanks

ive already instaled the hud into my car, the wires and connectors were all there, and I had a problem with it being too dim, I did the whole re-soder the photo-cell thing this morning, but in the daytime it is still very dim,

could the dimness (is that a word) be caused by me not having the HUD windshield, and is there any coating or anything I can add to fix that, cause the $750 price tag on the hud windshield is too much for my pocket book

I have the HUD winsheld in my '98 GTP and the HUD is still reasonably dim durring the day. I just assumed that it was normal.
-Hope that helps.
