How-To: 6 Hi Mod GMT900.

[uchi]

i did the mod to my 06 sierra and loved it. best thing i did to that truck by far. so i was digging around through here and found the old link i used to help me do it

real quick, is it the same pin layout and procedure for my 09 sierra as it would have been for my 06? i havent been able to find anything for my gen truck so i thought id ask real quick. thanks

actually what im thinking i just need is the 4 hi mod but i want the fog lights to stay on with the hi beams if i turn them on, im gonna run hids in mine for night time visibility and i dont think i want them coming on with the high beams but if i push the button they go on and stay on. again i havent gone out yet to see if the fogs turn off in my 09 when the highs come on, knowing gm they likely do.

Fogs do turn off with high beams

thanks bud, i just hobbled my ass around the truck on my crutches to find out before reading your reply, lol. is there a relay wire to cut that would keep it from shutting off? i know my old cavalier was wired like this and it was as simple as cutting one wire in the relay to keep the fogs on when the high beams came on. anyone try doing something like this with the gmt900s?
