+ 1 ^^^
I put a 12 circuit unit in my Z and had it all wired in, with the help of a local Z friend, in just one weekend... For under $200, it was well worth it. I just need to go back thru it and hook up the heater unit.
I was planing on pulling the air con / heater unit out, and replacing it with a Vintage Air unit, but have not made it there yet...
