i snipped the MS CAN line and wired can 1 to one side and can 3 to the other side then can2 is wired to the HS can and the arrows and back buttons wired to analong 0 and 1. but now i have another issue. my traction control light comes on when just idling and goes away when i drive could this cause that issue?
Well I've already written the code you need to use. Out of the box the CBT does not run the Mazda specific firmware, it uses a generic firmware.
Have you downloaded the code from Github and setup Arduino? You'll need to do that, then you can flash the CANBusTriple_Mazda sketch to your CBT. That will echo code between CAN1 and CAN3. See here for Arduino setup:
Then in Arduino open File > Sketchbook > hardware > CANBus-Triple > avr > CANBusTriple_Mazda and flash/upload.
Also seeing as you cut your CAN bus you need to enable the termination resistors on the CBT. Remove the Neoprene plug on the bottom and you will find three solder jumpers on the top of the PCB near the main header through holes. Jump the CAN1 and CAN3 jumpers with some solder so that your bus is properly terminated on both ends.
