I'M CHANGING A DX CRX TO A MULTIPORT FUEL INJECTION AND I HAVE A 1991 CIVIC HATCH WITH MUTLIPORT ALREADY. THE QUESTION IS CAN I USE THE WIRING HARNESS FROM THE CIVIC IN MY CRX SO THAT I DON'T HAVE TO BUY ANOTHER HARNESS?

 

You should use your original dx harness and modify it with the mpfi harness

u cant use the si harness from ur hatchback beacause of the climate control being the main difference. i have a fully converted dx to si harness that im sellin it came out of my 90 crx. only reason i changed it out was because i went to referee my car with an LS and i wanted a clean lookin swap. the harness looks great some of the clips where it bolts onto the chassis and motor (not sensors) are missin as it was converted from a dx. the harness is from head lights to tail lights. ill sell it for 165.00 shipped. lemme kno
