4WD light on speedo and D300 connection

I never reconnected the 4wd light when I did my engine swap a few years ago and now I was thinking I should hook it back up.

My questions are as follows:

1) Is the light activated by completing the circuit by grounding in the Transfer Case when it is shifted into 4wd?

2) Would Twin sticks have any effect on this operation?

3) I am worried I may have ripped that wire out a long time ago, does anyone have any pictures of the back of the speedo cluster with reference of the wire and is it just as simple as running a single ground wire to the connector on the TCase?

Thanks as always guys!

It's just like you said. Power goes to the bulb, the ground wire comes from the bulb and goes to the switch on the TC front axle shift rail. When the front axle is engaged, the switch shorts the wire to ground so the light comes on.

1) yes

2) no, the switch is on the front drive shaft side so unless you do the mod for 2wd low it will activate anytime you engage the outboard rail

3) sorry no picutre but it was a white wire that came up the center of the firewall into a 4 pin connector that also had the neutral start wires in it....

You can add a 2nd indicator switch to the shift rails and wire it to two LED's in the dash to indicate what position each output is in.

Don't mean to hijack but where can you buy the socket for the 4wd light? My grounding shield broke off mine. No big deal but I would like for it to work.
