04ctd Posted December 7, 2007 Report Share Posted December 7, 2007 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: http://www.dodge.com/bodybuilder/index.html 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. 8w-80-89.pdf 8w-80-78.pdf 8w-80-22.pdf 8w-80-20.pdf Quote Link to post Share on other sites
gschwenk Posted January 15, 2008 Report Share Posted January 15, 2008 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??? Quote Link to post Share on other sites
04ctd Posted January 15, 2008 Author Report Share Posted January 15, 2008 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.

hottwhyrd Posted January 15, 2008 Report Share Posted January 15, 2008 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 Quote Link to post Share on other sites
gschwenk Posted January 16, 2008 Report Share Posted January 16, 2008 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.

04ctd Posted January 16, 2008 Author Report Share Posted January 16, 2008 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...
