i have a 00 civic ex automatic, and im swaping a JDM B16A the distribuitor im going to use is a 00 ITR, the only problem is that the stock dist. plug is a 8 wire and the ITR is a 9 wire. 7 of the wires match up(color codes) but there's a gray wire on the stock ex harness, and onthe itr there is a blue/green and a blue/white wire. wich one goes toghether , and wich one stays unwired?????
