Ok im getting a 95 KA, tranny, harness, and ECU. I have a SOHC S13. I've done a sohc-dohc (both s13 motors) swap. There isn't much info on the sohc to s14 dohc swap. Most people use the intake manifold from the 91+ S13 KA's. I'd like to keep the 95 stock, so i can use the OBDII system. I know i'd need the DOHC cluster along with what I'm getting. but what else?!

-would i need to get the body harness from an S14 to use my interior things with the s14 engine harness and ecu?
-would i need to use the s14 climate controler?
-Which connecters from the S13 body harness are different from the S14 body harness?
-if i get 91-94 PS high pressure hoses i can have PS right?
-What should i do for the A/C lines?

I'd like this to be a nice reliable daily driver for now, and be able to use the OBD II connector to pull codes among other things. all help is appreciated.
