Baja designs has a reg/rec part number 12-203. They say that you dont have to do the floating ground mod to use this part. https://www.bajadesigns.com/NET/P-122003/Regulator%2frectifier%2c+(dc)+(unwired) Has anyone used this part on their 99wr400 with good luck. I would like to convert the bike to a DC system and add a battery to make everything work well on my plated bike. The main reason for doin this is to add a HID headlight and making the horn blow (if need be). I am sure that you need to remove the factory reg/rec and replace it with the BAJA designs piece. What wires do you use from the factory wiring to attach to the 2 yellow wires on the Baja designs reg/rec? Thanks in advance!!
