Finally rolling on this again.
FYI, "This" is installing an iSensor tank level sensor system to replace my failed seelevel sensors.
A couple days ago, I accessed the tanks on the Door side, and got wires run from the wetbay to the door side of the tanks.
This threadgot me answers about how to get the carpeted panels off and access the tanks. I used a long stick pushed between the black and gray tanks to pull a bundle of 9 wires through from DS to ODS.
I installed the iSensor sensors to the exposed face of the water tank, and to the forward side of the black tank. There was almost 3" of access so I got it done.
I also cut the existing wires to the "touch puck" in the little storage compartment, and connected to my new wires, I'm going to make this hot all the time rather than on the cargo bay light circuit.
Hopefully today and maybe tomorrow (good weather forecast in Port A TX) I will get the wetbay stuff done, install the second panel and gray tank sensor, hookup all the wiring, and get this done.
Also in the plan is to hook the wetbay light to always hot, with a pin switch on the door so "when you open the door, the light comes on!"
