i have a 2003 chevy 1400 4wd suburban ok ive seen some different articles and used the search here. but i am looking for a good safe way to run all 4 lights together on high beam i saw where people were putting diodes from number 85 of the low beam relay to 85 pin on the high side relay which powers both relays but is there a wiring kit u can do that with as well or another way

Somewhere I read a simple solution by grounding just one wire. I would suggest doing a search on this site or maybe YouTube.com. I was going to do it to my Tahoe but never got around to it. Good luck,

The one-wire grounding thing only worked on the 2000-2002 trucks. For the 2003-2006 trucks you have to use a diode or more elaborate setup.
