Does anyone know where I can find the wiring diagram for the electronic compass, primarily wire colors and instrument cluster hook up locations? I need the four prong hook up. My Haynes manual shows me two wires (wht/org & wht/blk), I need pin locations in the instrument cluster and pin locations in the compass connector. Any and all help would be appreciated.

 

Electronic compass side

White w/ light blue stripe = power from Fuse #F18 pin #3
White w/ orange stripe wire = compass + to instrument cluster pin #1
White w/ black stripe = Compass - to instrument cluster pin #2
Black w/ light blue stripe = logic ground ( also at instrument cluster pin # 4

Instrument panel side
White w/ orange stripe wire = compass + to electronic compass pin 3 15 on C220A
White w/ black stripe = Compass - to electronic compass pin 16 on C220A
black w/ light blue stripe = logic ground pin 18 on C220B
power is different on instrument cluster side. ( fuses # F27, F15, F1, F21 )

Connector C220A is a black 32 pin connector ( 2 rows of 16 )
Connector C220B is black 18 pin connector ( 2 rows of 9 )
Both of these appear to be cam lock connectors, like behind the EATC.

 

Thanx SSCULLY, I was hoping you would chime in. How do I determine which is pin #1 on the compass? Would pin #1 be the one closest to windshield, or the one closest to the inside of the cabin? The connector on the compass runs sideways, parallel with the side of the truck. I hope I was able to ask that clearly.

 

looking at the connector, locking tab to the left, so the pins are vertical

pin 1 is on the top.

 

Thank you very much. I hope to get this hooked up this week end and my pcm flashed next week.

 

SSCULLY-
If you could check out this picture and tell me if I labeled them correctly. Sorry for the fuzzy pic, sh*ty camera.

 

 

That is how the drawing on 150-69 shows it.

 

Thanx SCCULLY
That's what I figured, I just wanted a second opinion. Thanx again.

 

You are still waiting on that second opinion.
Asking me again is like a doctor telling you something, walking out of the room, re-entering the room again, and telling you the same thing, calling it a second opinion.

 

Very funny, and a good point. I should have asked you to confirm the pin location. Kind of like saying the doctor re-entered the room again when he actually only re-entered.
