1995 TopKick parking brake

[Tuck2056]

Ive got a 1995 Topkick 366ci manual trans. Ive the got the cable parking brake set up and hydraulic brakes. Parking brakes works well no slop in the cable no slippage of the parking brake. My problem is the aux braking brake light and the alarm keeps kicking on. Pulled the contact switch out on the lever housing cleaned it all checked the switch it works fine when testing re mounted everything and its all adjusted properly but still have the same issue. I've been over the cable routing and checked at the drum. The contact switch in the cab is the only I'm seeing. Can someone tell me what I'm missing? Any helps much appreciated

might be something about it on charm.li (website), which should have the full service manual for your truck.
