Im doing a B16 swap into a 91 Civic DX with MPFI conversion, it is my understanding that I use my stock engine harness, and just plug it into the B16 right?? Also do I plug the B16 into the connectors off of the old engine harness, or to the harness on the strut tower kind of confused on this? Pictures would be great. Can I run the 4 extra wires from the ECU to the connector on the harness?? Also my mount kit comes with three mounts, do I need any mounts off the B16?? or any off of my old engine?? Thanks alot for your help. Also do I need the rear engine mount bracket, and if so can I use the rear motor mount bracket from a 99 integra instead of a 90-93? Thanks alot for your help.
