Sorry for taking so long to get back to you, doing the holiday thing with the family. From what I read from both Transflow and GMC. When tieing into the purple, both the Trax gage and OEM gage will work. The purple should be the relay wire to the ECD, controlling the low fuel warning lamp. The Trax gage uses this wire to monitor and show the capacity of the stock tank. I'm going to say that you have the wrong wire, however, if you're dead sure you have the right wire, Transflow's web site has a listing for local techs or installers, you may want to give one a call. After all, it is an electrical device and they do fail even when new. Goes back to that whole "lowest" bidder thing.

    There are a couple of forum sites for people that have transfer tanks. You might try one and chat with other people that have installed them. Google: Transflow transfer tank.

Can't find Nav fuse

I have a 2008 GMC Sierra 2500HD Duramax and use the HyperTech software also. I assume you are talking about the installation instructions for HyperTech where it tells you to remove the ONStar and Radio fuse. Look in the owners manual for the fuse box layout under the hood. On mine, it's in the Duramax book and the only fuse that applies is the one listed for the Audio System. You will need to reset your clock when finished.
