I have now replaced my '01 CDL transfercase with a freshly resealed '04 transfercase. The '04 transfercase has two CDL sensors in the front output of the case, as opposed to the one sensor that my '01 had. I cut and crimped the old wires and attached them to the front most sensor on the '04 case, which is in the same physical location of the case as the old one and I just left the rear most sensor unplugged. The CDL feature works, but the light does not illuminate on the dash anymore. I'm curious if anyone else has run into this issue as well and if it was resolved by wiring into the rear most sensor instead of the front one.
On my 2001 D2 the CDL light has always properly worked after I did the D1 shifter linkage and the re-wire to the BCM (to make the TC/ABS not freak out when turning the vehicle off and back on with CDL engaged)
