| Tekonsha Prodigy brake controller
Just bought the Tekonsha Prodigy brake controller and getting ready to install it in on my 2007 Sierra Classic (2500 HD, Duramax, Allison transmission, 4wd).
The wiring harness that came with it says to install a 40A fuse in the J-case under the hood if the truck came without the TP2 (auxillary battery) option.
It also says to disregard the fuse if the truck came with the TP2 (auxillary battery) option. How do I know if I have the TP2 option. I have dual batteries, but I don't know if that is the TP2 option. |
