[Hezsus]

not sure, it should be in today or tomorrow and i'll post up pics then

Not sure what thread it was in but I saved the wiring info since I am planning on doing this as well.

Wiring Info

What the wires to the DIC connector do

7 = dark green - RAP Fused Supply
8 = black/white - Ground
9 = drk grn/wht - VSS
10= lt grn/blk - Outside air temp (this should be the only wire out of the cab to the sensor)
11= gray - Instrument panel lamp fuse supply
12= ppl/white - LED dimming signal
13 = NOT USED
14= Orange - constant 12v
15 = Yellow - Class 2 serial data

The connector for the DIC to the large A-pillar connector

7 (DK GRN) = P (DK GRN)
8 (BLK/WHT) = F (BLK/WHT)
9 (DK GRN/WHT) = N (DK GRN/WHT)
10 (LT GRN/BLK) = G (LT GRN/BLK)
11 (GRY) = E (GRY)
12 (PPL/WHT) = M (PPL/WHT)
13 = not used in the DIC connector
14 (ORN) = R (ORN)
15 (YEL) = C (YEL)

The large A-pillar connector to the Radio connector

P (DK GRN) = Radio PIN 9
F (BLK/WHT) = Radio PIN 5
N (DK GRN/WHT) = Radio PIN 16
G (LT GRN/BLK) = outside air temp sensor
E (GRY) = Radio PIN 7
M (PPL/WHT) = Radio PIN 6
13 = not used in the DIC connector
R (ORN) = Radio PIN 10
C (YEL) = to purple ALDL wire (OBD II port)

awesome thanks, I need a picture of the plug now though, I dont have the plug end just the DIC, cant see any numbers on the pin either.

Ok, I can get you one tomorrow if no one else does first.

BAM! a lot of googling resulted in this:

about halfway down is the diagram

I got a few pics of the plug. Pm me and I will email them to you, I can't figure out how to attach them from my phone....

 

[Hezsus]

thanks blue, i got it figured out though, my problem now is that everything is showing up with -- after about 20sec
i'm not 100% sure I found the vss wire either.. i went to the green/wht on the radio harness and the purple pin#2 on the obd2 connector, no luck though.. anyone have any insight?

Mine showed that when I bench tested it. IIRC the VSS wire is not actually a grn/white. its more of a light grn/tanish. I put grn/white because I thought mine was faded. Just count to pin #16 and use that one.

 

[Hezsus]

tried both pins 15 and 16 with no luck
I dont have the temp sensor or the dimmer/headlight lights hooked up either.. i didnt think they would make a diference

i'm also getting my power from pin #2 (whiteish) its the only pin that had switched power
