I have a 91 civic dx hb and I just put an ls non vtech motor in but the motors wire harness doesn't connect at all the connections. What do I need to do to make this motor work? Do I have to change out all the wiring in my car or is there something simpler? Hook me up cause man I can't take this no more. (yes I have the computer too.)

 

You need mpfi http://fourthgenhatch.net/mpfi.html. You also need a a conversion harness http://rywire.com/store/8891-crxcivi...f331ba92807b6e.

Lastly vtec. Not vtech.

 

actually is VteK, cmon nub
