Actually, it is a completely different procedure for the newer 2000+ Bonnevilles. Look in techinfo for another procedure specifically for the newer Bonny'*. Basically you remove the DLR relay then place a jumper across two terminals in the relay socket. The 2000+ cars utilize the high beams for DRL. In normal high beam mode the high beams are placed in parallel via the series/paralleling relay, when in DRL mode they are placed in series. The ambient light sensor provides input to determine DRL operation ie is night or day.
