checking out the electricall guide i came across this

what does it mean???

top unit is the nav dvd unit and the wires sticking out of it

just need to know what the circle around the wires means??

 

It means you need to use teh scanner. I have to idea what you drew.

 

It means the two conductors on the left are shielded.

 

the circles or dots? dots mean the wires are connected. i dont remember what the circles mean.....


i hope you are taking PLENTY of pixtures....there are alot of non-navi tsxers out here that may be considering following your footsteps.... you are paving the way

 

shielded by what???

my question is when i go to connect these things to another unit

do i gotta connect the wire to the right to the 2 on the left so that they are all 1 wire???? or that doesnt make a diff??

 

Shielded from radio interference, usually by a grounded braid over the wires.

With all due respect, without buying every wire harness that's required for a Navi car, you're fighting an uphill battle. Fabricating harnesses yourself will be next to impossible.

All symbols used in the ETM are described at the front of the manual.

My suggestion would be to quit now while you're ahead.

 

Dude... Keep going... Who cares if you dont go all the way, least you could do is resell your stuff on ebay. Worst you lose is some time..

You already have everything.. just keep trudging the path.

 

is this shielding really necessary

will it make a diff it i dont put that shit??? LOL

 

ok here is the real scan

i need to know what i do with the black circle

how do i connect those 3 wires

 

What that means is that there is a shield around the conductors, and if you follow it it's probably only grounded at one end. The audio lines out to the OR amp are done this way, and they are only grounded at the amp end.

Personally, I ahve crappy experience with shielding in ars, and I believe failry strongly that whether those are audi o lines or data lines, using twisted-pair cabling will solve any noise-pickup problems you might have.

Shielding with a drain ground wire at only one end is a noise rejection trick, and twisted pair is a better noise-rejection trick.

Can't read your drawing - is it audio or data?

 

honestly, i think it wouldnt be THAT bad making up ure own harness, yes time consuming but im sure if u connect all the right wires u should be set, but yes in a perfect world i would most definately go for the prefabbed harness, youd be an idiot not to want it

 

check it out now

 

so if i understand you

i can grab that light green wire which is the one showing all the shielding and take it directly to a ground spot right?? all i need is that special type of wiring???

 

All I have to say is I just got a high B (top 15% of the class) in Georgia Tech physics II (electricity and magnatism) and i have no idea what any of that means. That class was useless and a big pain at 9 AM. I'm just saying I might be able to help in about 2 years when i start doing stuff i'll actually need... and venting because i still have one final left.

 

No. It's just a shield. Probably internally connected to GND. Thus if you connect the other end directly to ground, you create a ground loop = inducted noise.

So, only connect one end to ground OR to the "SH" signal out the amp.
