Did your truck originally come with projector headlights? Either way, in order to use AlfaOBD to run the DRLs on these headlights and not the fuse tap harness, you’ll have to use the dedicated DRL circuit wires. If your truck came with projectors, it’s easier. If it came with quads, you’ll have to add the wires to the front end connector, which @Mpgrimm has a solution for, I believe (2 lengths of wires with the terminals crimped on). You can’t enable the turn signal as the DRLs for these, because it’ll just illuminate the amber turn signal light. These are the settings you would use:
DRL configuration >optional
DRL lamp location > dedicated
DRL dropout enabled > yes
CBC I/O right dedicated DRL lamp output present> yes (should be yes already)
CBC I/O left dedicated DRL lamp output present > yes (should be yes already)
LED dedicated DRL present > yes
ECUConfig 3 DRL customer setting enable> yes
CustSetMenu 1 daytime running lights CSM> yes
