I bought a 89 crx dx a while back, the previous owner swapped in the d16a6 and 5spd tranny, only thing is he left it dual point. Would it be easier to just swap in the full wire harness from an SI? Or get one made. Plus the ecu, dizzy.....? Any ideas are welcome

 

If you're not comfortable with wiring just buy a premade harness from a reputable company. To swap in an SI harness you'll have to swap the dash harness as well. If you are comfortable look in the 88-91 or hybrid FAQs for DPFI to MPFI conversion.
