Per Crutchfield, this is the wire to use with a D3.

 

Circuit K75, Dark Blue with Orange tracer.

 

All the Dodge truck wiring is here:

Many of the OEM drawings are wrong, incomplete, non-sensical, and wrong.

 

so, caveat emptor (you are getting your moneys worth)

 

Note the SRT logo on some pages, and some are for Diesel trucks on that site.

 

a significant problem with the files on that site is that they are in NO WAY marked for what year vehicle it applies to, once you down load it off that site.

 

so be careful. there's a reason Mercedes sold Dodge/Chrysler.

Lots of good stuff in there...I can't make heads or tails of it, and I'm pretty smart...my mom told me so.

 

I've got an '04 dodge ram 3500, diesel, dually, 6-speed manual, quad cab, 4x4 that I just had an N-4 installed on and I'm considering hooking the VSS wire on...I think it's coming out of the ECM connectors on the engine. There's 2 of them though and I can't figure out which one it is, and whether it runs into the cab or not. Does anyone have any experience on where/what I should be looking for??

 

Incidently, the installer and Pioneer both told be not to worry about it, it isn't really required...thoughts???

mine's not hooked up in my CTD, works fine.

 

you on DTR?

 

i would not worry about it.

 

i do NOT think it would come off the ECM.

 

the ECM is a cummins product with dodge programming in it,

 

it's not speed related.

HMMMM.

 

which adapter did you use with your d3?? if you got a canbus adapter than it may include the vss wire. on all dodges 2002 and up there is no vss. i think some diesels and non hemi's may have them but on all those trucks you have to either get an adapter or simply dont hook it up

Ok, I kinda thought those ECM plugs had a Bosch look to them. The N-4 was installed with the wiring harness from crutchfield.

 

The only thing I'm worried about is whether my unit will complete it's "learning". I heard that it'll never finish without the VSS wire.

 

No, not on DTR, but do a lot of reading over there.

the crutchfield adapter is the crappy metra.

 

there is a better one that does supply the VSS signal (per some posts on here)

 

mine works, never checked the learning screen.

 

it's only off the road in one part of town, and that's a remote road thru the backwoods.

 

 

i would run it a while, and not worry about it.

 

jump in the "breakroom" on DTR and tell some lies. it's good for ya...
