1991 Itasca 30ft cruise control
I have just purchased a ITASCA WINNEBAGO 1991 # 70F601249005 with a GMC Forward Control Truck K3500? 7.4lt V8 (vin 1GBKP37N8L3317314) and I have found that the low beam and the cruise control does not work. I am not sure who made the unit, but I have been told that the unit is a Control Switch and Lever Assy gm part 25031710. I have also found on the web Installations & operating instructions for a DANA's Electronic Speed Control for a 1991 GMC diesel for a Winnebago and it has the unit as a 58D-08X63-F. Dana has been sold and the new company does not have any of these parts. GMC says the part 25031710 is discontinued. Does anyone know where I can get a replacement part and what it would be called?
I would also like to find an electrical diagram for the GMC truck.
