Glenn,
Check the wiring diagram and you'll find that the OEM fuel gauge is fed by
a Gray wire with double black stripes. That wire is in turn fed by either
the Aux or Main tank sender, dependent upon the position of the fuel tank
selector switch. In your photo of the connector, the second wires from the
right, in cavity C, should be that Gray w/dbl black wire.
Connect the new gauge to ignition, ground, and that Gray w/dbl black wire
and you should be good to go -- IF the tank senders are good.

Hello Dan,
Thank you for your comments.
We just got back form our 3rd trip in our GMC.
We still are getting used to it, and love it more with each trip.
I was just trying to get accurate info from my engine and am currently installing quality gauges in our GMC. (A big thanks to Ken H !)
I feel very fortunate to be a member of this GMC community.
I have already learned so much on this forum, and we have joined the Sunshine Statesmen GMC club and have met a handful of their members (all so very nice)
I am hoping that next year, the Mrs. & I feel more comfortable going futher from home.
So far we head in any direction, but only 200 or so miles from home. As we are more comfortable with the reliability of our GMC we shall stray further, and hopefully leave the state of Florida by next year.
Hope to meet you in person one day.
Sincerely,
Glenn Gardner...G2photosmx.com

Okay
I need help also.
The field rats bit off the wires right at the opening coming out of the
floor on the outside going to "I think?" the fuel tank switch.
Who has the color code for the fuel switch.
I need to some how find the wires inside the coach and bypass the cut wires.
What a PITA
That's what you get when you live out in the sticks.
Thank You

Welcome to the group.
I hope you will experience all the good things Jan and I did over our many
GMCing years.
We spent all of 1977 touring the lower 48 with 2 pre teens in a new GMC. In
'93 we bought another GMC with over 400k miles on it and put another 200k
on it.
We made many friends, enjoyed great fellowship, travelled in every state
and province , garnered a lifetime of memories, and learned a lot in the
process.
Jump in with both feet. You and yours will never regret it.
Happy trails!
