factory/dearler installed 8-track players

[into69z]

I have been looking for an 8-track player for my 69 pick-up and finally found one. I have seen this underdash mount player in some of the literature for 1969 trucks. Now that I have one of these, I need infor on how and where they actually mounted, what the wire schematic was like, what color wire goes where, did it play thru the speaker in the dash or did the option come with additional speakers and where did they mount? I know it's alot of questions but I also know some of you have these units or have the info that I need any information on these 8-track players would help alot-Thanks Steve
