Distrubitor
 

Ok i got a 90 si.. engine harness in my car.. i put in a usdm b16a3.. im at the last step.. I ran into a slight difference in color wire.. ok i compared both distribitor harness and both have 6 out of 7 wires that are the same.. so i soldered the 6 but the last one i dunno if i should connect it.. cuz from the 90 Si engine harness its White.. and the 94 delsol vtec is yellow/blue i think.. what should i do.. Any help would be appreciated. (iM running p30 Ecu.. everythin is wired on the Ecu.)
