Headlight control module
 

Does anyone know if the headlight control module from a 2000 C5 vette work on a 1991 C4? '97 and later has a different part number than the '88-'96. But these parts look the same. Does anyone have a module for sale that will fit my 91? Thanx, James

88-96 modules all work the same no matter what the part number , dont have a clue bout the 2000

For future reference on this subject, the answer is NO. The HC modules look the same externally but are diffenent internally.
