Overhead Console - S-series

UPDATE

Finally started working on this today!

I used 2 wiring harnesses. Both were fully un-taped. One was used as the "good" one and the other was cutup and used to lengthen the other harness. I did this to keep everything in the factory color-coding scheme.

Little problem.....it's not working right!

Here's my wiring (from the DIC plug to the pins on the A-pillar plug to the radio):

7 (DK GRN) = P (DK GRN) = Radio PIN 9
8 (BLK/WHT) = F (BLK/WHT) = Radio PIN 5
9 (DK GRN/WHT) = N (DK GRN/WHT) = Radio PIN 16
10 (LT GRN/BLK) = G (LT GRN/BLK) = outside air temp sensor
11 (GRY) = E (GRY) = Radio PIN 7
12 (PPL/WHT) = M (PPL/WHT) = Radio PIN 6
13 = not used in the DIC connector
14 (ORN) = R (ORN) = still connected to A-pillar
15 (YEL) = C (YEL) = to purple ALDL wire

What's happening:
When I put power to the truck, the DIC displays everything with the key OFF (no data is calculated, but the display lights up and can scroll through everything). It displays nothing with the key ON/RUN.

I have absolutely no idea what's wrong. I followed all the info I found online and all the colors match up behind the radio.

Any ideas? Is there a discrepancy between my truck (a '98) and the colors that I'm going by?

Mine did the same thing, with the key off, it can't read the computer.

Double check your wires, and then check them again, make sure your splices are good...

Also, make sure you spin the wires your tapping into, sometimes there's a line that's a PITA to see, making it the wrong wire.

Post up what functions those radio pins are for, please... I don't remember splicing anything to my radio

7 = dark green - RAP Fused Supply (tap into DRK GRN, radio PIN 9)
8 = black/white - Ground (radio PIN 5)

11= gray - Instrument panel lamp fuse supply (radio PIN 7)
12= ppl/white - LED dimming signal (radio PIN 6)
13 = NOT USED
14= Orange - constant 12v (tap into orange wire, top plug of radio PIN 10)
15 = Yellow - Class 2 serial data (ppl wire at ALDL)

Ahh, yes, I tapped into the RAP at the radio, but that's the only wire... I used the instrument cluster for the VSS and the headlight switch for the lights

IMO, tapping into the radio harness for everything is a PITA

I also only ran "one" wire... I used some CAT5E.

My dash is out so behind the radio is SUPER easy.

I thought about CAT5E, but I wanted to keep everything factory color-coded. Plus, you'll never know unless you remove everything.


I'm just really confused right now....and I still need to figure out where to run the wires for the auto-dimming mirror to.

It needs switched power (or ignition), ground, and reverse signal (if I can find a convenient location to get that; or else I'll skip it).

Can I get the ignition power behind the radio? Or any where easy to get to right now?


Honestly, I don't see what's wrong with my current wiring. All the colors and descriptions match up. It's acting the exact opposite as it should. I hate confusion!

Instead of matching up colours to colours, trace from the OHC each wire, by function...

What I did was match the colors with the pin-out on the large A-pillar plug. I then labeled all the wires one by one as I cut them. I will try to re-trace them, but I didn't undo the entire harness the second time around. I left the foam insulation on the wires (kept them a lot neater).

Where else can I get a switched power source? It would really be cool if the OHC would come on when the key was turned backwards and to the RUN position (just like the radio does; then I could get a temp reading without turning on the fuel pump).
