what exactly is a shield wire and where would it splice to around 2 wire? i know this is a lil vague, but i can post a pic yet of what i am trying to figure out. but there are 2 video wires with a shield wire with splices right after each end connector. thanks in advance!!!

 

A shield is basically a ground. You would terminate the shields to the frame or any other ground.

You dont need to ground shields, but the purpose is to eliminate "noise" from other electronic signals and their interference.

So if I understand you probelm you just have one end that needs grounded? If the other end is connected to the video source and grounded , lets say to the case, you need to do nothing with the other end unless you want to. Although most sheilds are terminated to ground on both sides

Hope this helps, if you post a pic of the schematic I could help you decipher what it wants you to do.

 

i will have to print a copy of the diagram and take it to work tomorrow and scan it. basically i have to create a harness. i am trying to add the new rear camera. the wiring is there to a certain point in the rear, but i have to make the rest and that is the only thing that is throwing me off. is it really needed? i mean i am looking at 15in of wire that would be without it. thanks for your help....

 

A sheild is useless without a ground. You can ground just one side and it should be fine. You can ground both sides, but you dont want current passing through your sheild, so be careful what you do.


Solid core wiring, sheilding and twisting the pairs all reduce noise. You can buy some sheilded cat 5 and that would probably cover the application. You can also get some sheilded J/K or probably some closed circuit wiring that has a grounded sheild. Cat sheilded cat 5 is both sheilded and twisted, so it should give good noise protection.

 

i have the schematic scanned and ready to load into my gallery, but the galleries are messed up again and it wont let me load it right now. i will keep trying!!!

 

here is the diagram, i need help with the shielding along the left side or bottom of the page is you look at it the right way. thanks in advance!! WOW, didnt think if would be that small....well it is in my gallery also!!!

 

Here's a better picture.




Now, what exactly are you trying to do or figure out?

 

Ok lab here's what I see.

You have two video lines from the camera to the monitor. The sheild is coming out of the camera from pin (or wire) 2. According to the way the schematic is shown, this shield is open ended, only grounded at the camera.

If not already spliced you will take the shield from video + and video -, splice those two together and then run the shield to pin two at the camera.

Does this answer your question?

 

yes and no...lol.....ok since q was able to get a better pic, i need to get from C406 to C411 with out having to buy the $400 worth of ford harnesses. i can do the ground, power, but the shield is getting me. i know what i need to do, but what do i use. i went ahead and bought the harness from C219 to the mirror since it was $20 to do some research, but that has the open end of the shield. i guess i can take those wires and splice to the open end of the shield to close it and use that as my harness for the video wire, but what kind of wire do i use. it is gray compared to the the copper color of all the other wires in the harness. i hope this makes sense, but that is what i need. thanks guys!!!

 

Aluminum foil makes an okay shielding material. That's what the factory stuff Ford uses looks like, kinda, it's just a lot thinner, like tissue paper thin.

Conversely, you could always try it without the shielding and see what happens. I take it you're trying to add the back up camera?

 

I agree, try it without the shield. I didn't know you had to purchase all this stuff. You should not have any video problems not having one. Although if there is interference, thats where its coming from.

 

Hey quinten, any idea why there are leads from the rearview mirror to the power mirrors?

Also, if my memory serves me correctly, your a ford tech right?
(just wondering so that i could ask you for a wiring diagram lol)

 

yep, that is what i am doing......i guess i will try it with out it.....i bought the 14334 harness and yes it has the foil like stuff and then it is taped over the length of the wire to almost the end. i was just thinking if they put it there, it needs to be there. if i do need it, how would i attach a wire to the foil like stuff, or do i just need it to touch it to contiune the shielding?

now i just need to know how to get the front of the headliner down so i can change out the harness for the mirror and it feeds the vanity mirrors. if it matters, i do have the moon roof.

 

i believe it is for the auto dimming driver mirror, just like the auto dimming rear view mirror....

 

Quintin---can you buy just some pins, both male and female? or do you have to buy a connecter and take them out? also, how many differnt sizes are there? the pins on this harness i have wont fit together so i am quessing there are differnt sizes. do you think, or know where i can buy the connector to certain harnesses? that would be easier and i can just cut and splice together than adding and changing pins. thanks for your help, i almost have my research knocked out......
