Alright just went to the junkyard today and J30 stuff WILL NOT WORK for an s13, only things that you can use is the ambient temp sensor and the cabin air temp sensor with aspiration tube, you cant get the blower speed control from a J30 so it would make it a huge PIA to source out several different cars to get all the parts from, just find a early 90's maxima with DCC. Just letting you guys know they are very hard to find though, the you-pull-and-pay by my house had about 20 early 90's maximas and only one had DCC.
