Anyone Hack the RR Diff lock light to be used with Air Locker?

I thought this would be a kinda cool idea. if when I flipped my air locker switch the RR Diff Lock light would illuminate on my dash.

So I took my gauge cluster out and found where I bulb should be for the RR Diff Light. A quick run to Toyota and I had a socket and bulb for the the gauge cluster. I then traced the circuit to see where to connect a wire to. I stuck a wire in to the one that connects to the light. Whenever you ground that wire the light turns on.

Here's a terrible diagram.


This is what happens when I ground the wire, I was in 4WD.


The switch for my locker has two grounding wires, one power wire, and an on/off wire that goes to the solenoid on the air compressor.

Is there any way to wire the light into my locker switch so it turns on when I turn the locker on?

 

40 minutes later bump. Haha

 

If I knew more about wiring I'd chime in, but here is a free bump.

Actually, I might as well take a stab at this. I'd say splice into the hot wire from the switch and connect that to a relay. hook the ground from the light, and a ground from the body to the relay. Then I guess flipping on the switch would turn on the ground, thus lighting up you little bulb.

But that's a semi-educated guess right there, not sure if it'll work, or if it will make you burst into flames...

 

Actually I accomplished this today. Using a 5-pin relay connect the following
30- ground
85- ground
86- the wire connected to the light
87- the wire that is hot when you flip the air locker switch

Super simple and costs less then 10 bucks

 

Heck yeah it worked! well thats good, now ima go be an electrician, jk.

I knew it could be done though.
