Hi all, am rebuilding my dash after my rig was raped. Took the opportunity to install a CDL switch. Everything's back together (except for stereo), but... when I hit the switch, nothing happens. I can hear a fairly definite 'switch' sound coming from behind the instrument panel (I think), but there's no engagement in the t-case, and definitely no indicator change in the panel. Fuse is not blown, its good. Do I need to problem solve underneath at the t-case?An aside: when I shift to 4L, should I get 'low' on the panel (cause I don't but from my manual I believe it says I should)? In doing a search, I got so many variable that I'm confused. Also on Cristo's site there's a FAQ about an ABS mod related to this? What's the deal there-- I don't think my rig has ABS (it definitely doesn't work if I do) though I do have the light on the panel when I start up.... Thanks for any help. Cheers.
