Hey guys,

So we went to visit Randy's parents this weekend, and on our way out of town we ran by his dad's shop.

SO his dad pulls me aside and starts asking me if I want some stuff for my truck. He had an '03 7.3 that he traded in on a 6.4...but pulled his goodies off before he traded it in.

This is the cool one:



I know there is a writeup on how to install these, somewhere. My question is, was the digital rearview an option on the early 99?, and if so, will I be lucky enough to find a wiring harness in the headliner somewhere?

He also gave me some really neat grill blankies, summer and winter, and a fold-up tailgate step ladder.

 

No rear view back up system for the early 99s, and the only way you could get a compass was witht he overhead console on the Lariats. you will probably find a wiring harness in the headliner, but it probably wont be compatable with the mirror assembly.

 

Thanks Brandon. I'd be happy to find power...if I have power I can make it work.

Ive always wanted a temperature/compass mirror. I'll feel all high tech now.

 

Chris (F350-6) installed a Gentex on his truck. He may have the wiring diagram for it. You can pick up switched power on the same wire that is used for the guages.

 

Lisa, maybe this will help you. I think you can find the wiring separately and just install. It is stand alone and doesn't require anything from our early '99 trucks factory wiring. IIRC the compass is internal so all you have to run is the power and the air temp sensor wiring. Hope that helps.

Cool. Thanks guys.

 

As most said here, nothing in the headliner ( I was just there recently) but you can find a plug behind the kick plate on the passenger side.. Have fun with the install Lisa!!! Great time to install cab lights while you are there.. if you dont have them..

 

Nice find, Lisa. I love freebies as well. There is a plug in the passenger side kick panel and there's at least one key-on power wire there.

 

I am finally getting around to thinking about installing this mirror.

Anyone who has installed one have the wiring diagram that came from the manufacturer? I am electrically retarded and would like to see it.

OR...i would love to have the email of the guy who is selling these on ebay. I am searching ebay and having a hard time finding him. I searched Genex and all I found was a bunch of golfing crap.

 

Try it with a T Lisa. Gentex.

 

I did some searching and found this for you It all depends on the model # and the # of pins or wires that the mirror has on it



PIN 1 PINK POWER +12 volts

PIN 2 BK CHASSIS, GND

PIN 3 LT GRN BACKUP LIGHTS

PIN 4 GY TO AUTO DIM OUTSIDE MIRROR

PIN 5 PINK TO AUTO DIM OUTSIDE MIRROR

PIN 6 DR GRN/WT TEMP PROBE

PIN 7 BK/WT TEMP PROBE


Update on the GNTX-126...

GRY = +Output to side dimming mirror

PNK = -Output to side dimming mirror



GNTX-104 p

WHT/RED = Accessory +12vdc

PNK = Constant +12vdc

BLK = Ground

VIO/BLK = +12vdc reverse inhibit input

ORG/WHT = Active low transistor output from auto headlights function

BRN = Second active low transistor output from auto headlights function





Edit:

This is all I could find for the 177 Lisa, they all claim to have colors on the wiring not all black like yours. Were going to have to have you check it for pin #'s

The connections to a Gentex mirror (with comp and temp). The connector pin numbers are found on the wire incursion side of the mating connector.

GM / wire harness color / function
PIN 1 / PINK / POWER +12 volts
PIN 2 / BK / CHASSIS, GND
PIN 3 / LT GRN / BACKUP LIGHTS
PIN 4 /GY / TO AUTO DIM OUTSIDE MIRROR
PIN 5 / PINK / TO AUTO DIM OUTSIDE MIRROR
PIN 6 / DR GRN/WT / TEMP PROBE
PIN 7 / BK/WT / TEMP PROBE

Note: Pin 3 is to be connected to the backup lights to turn off the auto dim feature in reverse.

I have been told that "If you intend not to use this feature connect the LT GRN wire to chassis ground. If this pin is floating the auto dim will not work properly." I have not connected this yet and it seems to function propoerly except of turning off the auto dimm when the vehicle is put into reverse. Hope this helps.



******IMPORTANT *******
DO NOT CONNECT THE LT GRN WIRE TO GROUND. THIS WIRE IS 12V WHEN THE VEHICLE IS IN REVERSE. YOU WILL BLOW A FUSE
