R34 Custom mfd external AFR wideband, boost gauge

Hi, I’m currently working on replicating a mfd for my r34 so far I have made templates for the custom gauges, running Nissan data scan, now step two of the project, is to run a external wideband and a boost gauge if someone could point me in the right direction?
In the future I’m planning on having the mfd on the gtr location so far running it on my android deck
