I have an 89 crx dx and I was wondering what would be the easiest way to do the dpfi to the mpfi vtec wiring? What wiring should I use? What should I do about an ecu? Does anyone have a direct plug and play harness for a dx? Any info or suggestions would be appreciated.

 

I would suggest you use this:

let me tell you i searched hella hard on here to find anything and pretty much nothing on here helped me. had to resort to google for help. boooo to Honda-tech for helping us with B16A into DX swap info

but i have a few sites for ya

http://www.fourthgenhatch.com/mpfi.html
http://tech.hybridgarage.com/tech/index.html

thos sites helped me do it a whole lot. i finished the swap yesterday so if you have any questions feel free to PM me about it. Or you can go to http://www.hasport.com and send in your harness and have thm custom make you one for $250. Let me tell you this swap SUCKS but its not too hard if you pay attention.

GOOD LUCK!!

 

I believe the search function is not working right now.
