(possibly all years still need to confirm wiring) 


This is a zeeltronic A02T cdi unit. the cdi is fully programmable with the zeeltronic programming cable (sold separately) This Duel map cdi allows you to set the spark timing curve, rev limit and more. 


This ignition will come pre-programmed with the updated high performance DRW base curve for map 1 and a mild curve on map 2. Both curves have room to grow for future needs.


This kit includes the following.

A02T zeeltronic cdi wired and programmed.

Zeeltronic mount for the cdi to mount the the oem cdi mounts.


INSTALATION NOTE:  the stock cdi for a 400ex does not use dc 12v power and this zeel does, the two red and black wires from the cdi are those power wires. This is ment to Jumper in between the neutral light and the harness for power (this is black on the oem harness and is the red with the short black wire on the end on the cdi)

The darker green is ground (-) and it is the ground headed to the handle bars. The connectors on the oem harness are bullets and these cdi units will simply plug in to them and borrow power for the cdi from there. 


Not Included are,

1)Tuning cable.

2)Map switch.
