Low beams on with High beams?

[88sub4x4]

I have a '05 2500HD with autoheadlamps. I want to hook up my low beams to turn back on when i use my high beams. I have done this on many trucks before, but I am unsure if the auto headlamps will get messed up. Has anyone tried this on theirs?

Its very easy to do, let me look up the article I found, basically you use a diode and thats it...

a diode eh? i thought it had to wired up with a relay, but thats what i have been seeing on this topic. So i take it with the diode, you modify the gm circuit board to activate the relay? hmm, i wonder if i will find this thread with this diode you speak of.

I got sidetracked, Im looking as I type this, you use the diode and it ties two wires together in the underhood junction box...

Here ya go guys, I did this to my dads '04 Avalanche, and nothing has changed on the lights as far as I know. Basically you are just using the diode to connect the two wires together. If thats not good enough I can always take a picture of my dads..

Thanks for the info. I will see if it works on my '05. Seems alot easier then soldering in a relay and cutting up the factory harness.

Thanks for that link. I followed their idea, although my wire coloring was different, and I now have All 4 on high. It cost me $ 0.64! And I can do a second truck since the diodes come two to a pack! Thanks again.

Glad you got it all hooked up...
