I didn't finish the dash illumination system, since you said yours works, and it's on a different page of the workshop manual. |

Do you mean 1 to 3? __________________ Best Car Insurance | Auto Protection Today | FREE Trade-In Quote |
On the large connector,
99 position 1 is fan speed 2 93 position 4 is fan speed 2 On the small NB specific 3 pin connector, position 1 NB goes to position 3 on the NA large connector. That's +V to illuminate the a/c on indicator. I assume the R/B and G/W 2 position connector you have pictured is the NA dash illumination harness. |
Ok, I think I understand and If I do then I have it all wired correctly. I think all I need to do is ground the NB3 wire which is blue/yellow?
And where should the diode go? And in case I'm reading this wrong NB2 and NB3 both go to position 2 __________________ Best Car Insurance | Auto Protection Today | FREE Trade-In Quote |
If you ground NB3, then the a/c comp can run with the fan off.
Suggest you continue to study the diagram http://img209.imageshack.us/img209/5383/acstuff.jpg |
Just so I'm not mixed up I labeled the pins....
Pin 1 on the HVAC side goes to Pin 4 on the NA harness Pin 2 on the HVAC side goes to Pin 5 on the NA harness Pin 3 on the HVAC side is empty Pin 4 and 5 go to the lights Pin 6 on the HVAC side goes to Pin 7 on the NA harness Pin 7 on the HVAC side goes to Pin 8 on the NA harness Pin 8 on the HVAC side goes to Pin 6 on the NA harness NB1 goes to Pin 3 on the NA harness NB2 goes to Pin 2 with a diode on the NA harness NB3 goes to Pin 5 on the NA harness __________________ Best Car Insurance | Auto Protection Today | FREE Trade-In Quote |
It probably works either way, but I think putting the diode on NB3 is a better idea, after actually looking at the diagrams.
That's why I put it there on my pinout. |

Does not compute.

NB3 goes to Pin 5 on the NA harness
Pin 2 on the HVAC side goes to Pin 5 on the NA harness Both go to Pin 5 on the NA pig tail __________________ Best Car Insurance | Auto Protection Today | FREE Trade-In Quote |
Got ya. You want the diode in line on the jumper between NA5 (main harness) and NB3 (a/c switch harness). You do not want the diode in the fan speed circuit.
Run the jumper from the NA harness 5 to NB3. Cut that wire, then put a diode in it. Note that the diode is directional. The banded end goes away from the a/c button. |
