Wiring in 2 relays to the headlight's

OK guy's this ? has been asked I don't know how many times. Who has the best head light wiring with relay's.
I decided to do it myself with $13.00 worth of parts from O-Riley's auto parts.
2 relays
16 count of the yellow spade connector's
1 30amp fuse link holder
Here is what I did.
I figured out from my shop manual that both the low & high beam work off the driver's side light, so I cut the incoming green & grey wires off the connector, then put longer peice of wire to both relay's. This will activate the relay not much load so the wire can be same gauge as factory. I didn't run a heavy gauge wire to the passenger side light but may do it later on. I don't see any reason to but you never know.
Light connector:

Here is the relay's mounted with all the connections done. The one mounted high is for High Beam the lower one is for Low Beam.

I ran a good gauge hot wire with 30 amp fuse holder in line across the radator support to the battery and split off to both relay's. Then ran two grounds for each relay. I then added some length's of wire from each relay back to the connector on the head light. Took me 2 hrs to do it. Hope this helps other's who want to do this upgrade. I used butt connection's or spade connections with black tape on everything and wraped everything in black tape when done.

Get out and drive the truck this summer and have some fun!
It sucks not being able to hear!

LWB trucks rule, if you don't think so measure your SWB!
After talking to tech support at Air Lift I have found out that the kit I need is 60811. Per the measurements I gave them. Ride height of truck inside spring and inside diameter of springs.
