Hello Gents. I recently swapped my 1992 Zx7 J2 engine for a 1997 zx9r motor. Everything went very smooth, today I decided to finish up this project with wiring in the ignition box from the zx9 into the wiring harness of the the zx7. I have read that they are the same with the exception of the two plugs that go into the ignition box. to my dismay.......the wires seem to match up by color with the exception of an extra wire from the zx9.......black wire with blue stripe. where do i splice this extra wire in?????????? any help will be most appreciated.

As I said in messages, you should use the ZX9R harness with all the sensors when making this swap. The J ECU timing curve will make you lose a lot of power.
