There are 2 main wiring block connector types.
One is a 6 pin and the other 8 pin.
8 pin has self leveling and the 6 pin configuration does not.
JDM models are predominantly 6 pin.
You can fit 8 pin headlamps to the 6 pin wiring loom, however you will have to alter the wiring, however you will not have self leveling as the 6 pin cars do not have the leveling device which is located on the rear subframe.
