Hello all

I am getting ready to install AVIC-Z1 in my car and need some help. I have 1993 Lexus GS 300. Can some one help me with the 2 wires that I cannot seem to get any information about? I have searched the forum but no info
I need to know where and what color wire in the car is for speed signal input.
Second question is regarding the reverse gear signal input wire. Can I hook this up in the car somewhere rather than going all the way back to the trunk and hooking it up there?
Third question is regarding the double din cover plate. does any one know where i can buy one from

Any help with this will be greatly appreciated.

thanks

Xeeeeeem

I'd like to see pictures of the finished product!!
