Need circuit board help!

[shelbyluvv]

I have the rear defog/OD board out of a 93 ZJ. I am trying to mimic this on my MJ with a 5.2 Magnum.

I have blacked out all of the rear defog circuits. All I need is the OD circuit layed out. My plan is to use a WJ shifter with the OD off button on it. I also want to use the Shift light on a 94 XJ dash cluster. I will use an LED bulb in the socket.

Back of the board

Front of the board

D2 is a diode (what kind?)
R2 is a resistor (what kind?)
SW2 is the OD switch
LE2 is the OD Off LED

I'll only be using pins 4-7 for the power and what not.

PIN 4 is fused power
PIN 5 is Trans OD lamp PCM 37
PIN 6 is Trans OD pressure on PCM 10
PIN 7 is ground

I have a good idea of how it works but I do not know anything about resistors and diodes.

Can someone pleas lay this out and tell what diode and resistor I need?

Really all you need to is to install the switch, then wire in the led where you want it. The resistor should just be to get the correct operating voltage for the led. You could probably just get a little led bolt or something to put in the cluster, but I would check what the pcm is putting out for voltage on that circuit.

This is what I came up with after spending most of the day staring at my truck's wiring and all my diagrams.

Between the XJ, ZJ and WJ wiring the wiring should be correct. I researched the resistor colors and then tested it and the resistor should be the correct one.

All I need now is to figure which way I should put the LED in-line to make sure the polarity is correct.

Use the diode test function on a multimeter, you can figure out which way current flows.
