Does anybody have a Jetta S and would like some info on a cruise control install? I just added cruise control to my Jetta S with oem parts and I still have the part numbers along with wiring diagram info and coding info.
I work at a VW dealer so I got the parts at cost but here is a list of parts you will need with our dealer list prices. The switch part number is 5C5 953 513F 9B9 and lists for $122.00. You also need 5 wire terminals part # 000 979 009E at $8.50 each. One wire terminal part # 000 979 030E at $24.30. One butt connector part #000 979 941 at $3.90. Six butt connectors part # 000 979 940 at $3.90 each. And approximatly 3 feet of bulk .5 mm wire part # 000 979 981 at $1.50 a foot. These are the VW OEM part numbers that I used to install cruise on my 2013 Jetta S.
Im sitting about the same, i'd be interested in seeing the diagram as well as pics of the install how it sits now. Nice job though, i was seriously thinking about doing this as well. Now if i can just figure out how to wire in the audio controls from the steering wheel and get the cruise wired in there.
I did not take any pictures while I was doing the install only because I was trying to get it done as fast as I could. I can't get the wiring diagram on here but I can tell you where the wires need to be installed. Also all the pins at the connectors where the terminals need to be installed were empty so I just simply installed the terminals (but there was a fake terminal plug in the ecm connector that needed to be removed before installing the terminal). Pin 3 at the cruise switch connector goes to pin 47 at the body control module (J519) connector 73b. There are 2 connectors at J519, connector 73b is white and on the left when sitting in the drivers seat. Pin 5 at the switch goes to pin 46 at the 73b connector. Pin 6 at the switch goes to pin 44 at connector 73b. Pins 2 and 4 at the switch need to be bridged together with one wire then going to pin 45 at the 73b connector and one wire going to the 94 pin ecm connector pin 65. There are 2 connectors at the ecm, the 94 pin connector is the big one. After installing the wires J519 coding needs to be changed and the ecm needs to be activated for cruise. The fourth bit in the J519 coding goes from 18 to 9A and the eighteenth bit goes from 42 to C2. J519 needs to be coded before activating cruise in the ecm or dtcs will be set in the ecm that will prevent the cruise from working until they are erased, trust me on that one. I have access to VAS PC so that is what I used for the coding changes and activating cruise in the ecm.
I just finished putting cruise control into my sons 2011 Jetta S (2.0L, manual, US model, base, no sunroof). I thought my experience might help others.
First, I do have the -086 Body control module. I bought a -087 off ebay since many threads say that you need it but in my experience it the -086 is fine. I t had all the pin locations and software. If youreally want to have an 087 handy just in case..let me know I have one that works.
Second, In the long coding VWMaster31 spoke of "9A" being coded in bit 4 and a C2 in bit 18. Only the 18th bit (which coincides with a "cruise control" check box was needed in my install. Well that and the ECM (code to "G" i think)..
Third, Verebs1 and VWMaster31 both specified the same wiring connections. I used Verebs1's wiring harness. I have to say that Steve does a nice job making that harness. Looks OEM.
Fourth, I used the VAG COM locator map (found on vwvortex) and then emailed 4 local guys with the software. All four answered quickly and offered to help. Gotta love this VW community!
Fifth, I used a stalk off a bug and the steering wheel removal tutorial (on this site and referenced elsewhere in CC/jetta s discussions).
I only had one issue and that was a piece of debris in one of the plugs that kept a wire from seating. I placed that wire late at night and didnt pay attention. it took me several hours to trouble shoot.. I stress that that was due to my own ignorance. Most difficult part of this was counting and locating the pins. Reading glasses and a forehead mounted LED light might have looked stupid but made the job very easy.
Removing the trouble shooting (my error) and then counting the time to complete and it was only a couple of hours. In fact since i now have experience from troubleshooting...I could probably complete in 45 minutes with harness in hand.
Conclusion: It can be done. It is not expensive. Ask for help and allow extra time if inexperienced.
I have read and verified that aftermarket Rostra system requires the factory radio be installed due to wiring required for can hi and lo at the radio harness. For those who have retrofitted a 2014 Jetta with original parts are you aware of a requirement to have the factory radio in place?
Thanks in advance for any advice.
