K1600GT O2 Sensor Connector Location

A friend of mine just bought a 2019 K1600GT. I'd like to help him with some projects he's got in mind. One of which is to try a pair of AF-XIEDs. I've got little experience with this model and I'm wondering where the O2 sensor connectors plug in, and how best to access them. It appears they're under the tank but I'm hoping they can be accessed from the side. Any insight would be appreciated.

Route cable (1) for the oxygen sensor between engine (2) and gearbox (3) and secure it.

Appears to plug in behind frame spar by left knee position.

Thank you. That’s a great help. Another reply suggest that the tank probably doesn’t need to be removed.

Hey Roger,

I would be interested in some follow up as I am considering adding af-xied to my GT as well. I have one on each of my 01 GS's. location of connections and how it changed the performance. if you can would be very appreciated.

Thanks,

Roger said he would be posting results on K1600forum.com

I placed this post on the K1600 forum as well. installed the af-xied on my 16 K16gt last night. pulled plastic panels as if doing air filter change but stop at just the side panels. no need to pull the center piece. the o2 connectors are obviously displayed and fastened just about knee level. plugged in new harness and routed it just under the front seat mounting piece. used Velcro to secure the af-xied controllers just past battery and metal cross brace to top of inner fender. about an hour start to finish. after looking at it didn't think pics would be necessary.

Did download any operating data prior and post to the install that could be analyzed and graphed as Roger hasn’t done in the past?
