My gear controller worked but it always retracted the landing gear upon powering up. This is not ideal, I had a LG15 in my shop, and replaced the stock electronics with it, It works much better.
I use a bus connected Cortex Pro. I use port six for the front steering. So the Cortex is controlling steering. I think you can tell the Cortex to not stabilize a single port and then run the signal thru the brake gyro, if you didn't want the Cortex to do it. That is a way to avoid a wye cable.
