when using this harness on a dx EF do u still have to convert to multi point first??

it looks like on mine there is an xtra clip added in where they added the other 2 injectors on. but i have never used a obd0 to obd1 conversion harness.

all i know is the car at one point had a running mini me obd 1 in it

my car wont start now so im running down all the problems it could be.
