The 6 spark/inj ctrl wires go to ECU. Follow the link(s) for pin detailed info http://www.cardomain.com/id/pohjola#links

For ECU location check http://www.cardomain.com/ride/748507/15 , (pin -info is for 3gen)

.

Update:> I found the wiring diagram for the spark plug wire harness, and it looks to me that there's no other component between the harness wires and the Engine Control Module (ECM). If this is the case and there's no short in the #5 plug wire, then the problem has to be the ECM itself. If you can confirm this, it would be a big help to me. Holla back!!!!
P.S.> Do you know of a good price reasonable source to purchase a ECM/ECU from? Can the logic chip in the ECM/ECU be removed and replaced?
