Tow haul light not working

[xpbprox]

So recently I put custom tunes on my truck. I bought the SCT used off of here and the did not know what his strategy was but I got it anyway and I lucked out on the strategy and it was able to work on my truck. The only problem I have is that after I put it on my tow haul light disappeared and does not come on but I can feel it down shift and I know when it's on. Any ideas? Maybe coincedently some fuse when bad?
I hope I posted this in the right area
