4 way High Beams

[silverado3500]

I Just did the install as described here on my 3500, using a $6 radio shack 30 amp relay.  With one difference, I wired a toggle switch in line between the orange wire and the relay, this way, I can override the 4 ways, if i don't want it that bright.  The end result is like having 3 settings on the headlamps  Low, High, and ultra High!

 

Here are the instructions that I went by.

The 1500 is next!

 

P. S.  Does anyone have the wire schematic for the headlamps on a 88-98 1500 with the composite (dual) headlamps.  I'd like to do the same mod on my 96, but am unsure which wires are which.
