Intermittent Fuel Gauge

'06 magna 630 fuel guage inop. Replaced sender and checked continuity as far as I could, but could not locate Borg Warner controller, (DC4 harness goes from electronics bay to this unit and from there to both the silver leaf and the fuel guage), to check continuity. Somewhere in this wiring mess, the wire 37 from the fuel sender changes to a cat5 cable. My next step is to call Medallion Inst. Sys. anc try to get the wire codes and values at the harness going into the guage. Any ideas?

I just learned for the umpteenth time to check the ground connection.

Doing so would have saved some parts money and time on my recent foray into electrical problems.

If already done, then you perform much better than I did.

My fuel gauge reads full all the time until the tank is getting close to E. If I see the gauge move then I have about 20 gallons left. I normally don't let it get that low but it happens once in a while. I'll reset the trip meter and stop for fuel when it gets between 700-800 miles.
