You are going to need to completely re-pin the plugs, which is not recommended, your better off doing a DPFI-MPFI swap, this envolves modifing your stock DX harness to work with MPFI engines. Its really not that hard.

VERY TRUE.....i've seen some people try to save money and try wiring the whole car to an si....woweee. the project took over 2 months of trying to figure out wires and where they go. but i guess if you want it to be a real si harness...more power to you. but stick with something that works...and works well. good luck

I have done BOTH I will tell you NOW convert your DX harness to MPFI it is not that hard its realy not. takes oh about 1 1/2 hours for the first time I can knock them out in about 45 mins now... I use a diagram found at hybrids web site
