Ok I have the d16z6 harness, the plugs that go into the p28 and i'm using the instructions that are on http://www.thezcr.com . The one thing i'm not sure of is do you have to run more wires through the firewall to the ecu harness since there are more wires on the d16z6 than the original motor came with? Also if you do is it just a mater of conecting the same colour wires together or do some of them split off. Thanks in advance.
