03 2500 Oem Fog Lights Install

[777stickman]

Going to help a buddy install OEM fog lights on his 03 Sierra 2500 HD. We got the kit. The directions are pretty straight forward and easy to understand. The problem is in the wire hookup to the underhood BEC(bussed electrical center). The wire goes into the "forward lamp 32 pin connector" under the BEC. The wriiten instructions say to put the wire into receptical "D6". The picture right below that shows recepticle "A4". Can anyone tell me which one is correct from an 03 and up service manual wiring diagram for the fog lights? Thanks.........Steve
