Hondata

i am stuck on how to wire my plx m300 to my hondata s300 for data logging. i have tried searching on various forums and came across different answers. i have hooked up the power to my fuse box and the ground right next to the ecu. what do i do with the white wire. i was told i need to do something with a capacitor or something. can anyone tell me the proper way to wire this up. thank you.

thanks alot. i dont know how i missed that!!
would running closed loop effect anything negatively? i am running a stick gsr map right now on a lsvtec. does the ecu use the wideband to instead of the stock o2 after removing it? how do i know if i am getting accurate readings from my wideband. sorry for all the questions i just dont want to mess anything up.

No it will not have any negatives. YOu can use either the narrowband or wideband to run closed loop.
