I'm trying to get ACC (S5DFA) retrofitted on my G30. I have S5ASA and S5DNA, so I don't think I need a new DSC module or the SAS module.
Assuming this, I would need the radar sensor, radome cover, bracket for sensor, grille with cutout for radome and mounting hardware for bracket. However, I cannot seem to wrap my head around the wiring harnesses required.
I know my car already has some wiring harness for the front-end/bumper for the active shutters and the PDC sensors. Bimmercat (
https://bimmercat.com/bmw/en/search/...58/USA/61_5010) has two P/Ns for the wiring harness, 61129395453 (set of cables, front bumper) and 61129855638/61126991536 (cable set, front end). Not sure which of those two I would need.
Any insight would be much appreciated!
That
guide from the Russian guy seems pretty good. It's just I am still confused about the wiring harness required.
The wiring diagram for B202 (connector for the ACC radar) seems to indicate 5 wires which need to be connected to different modules. The connector itself is 8 pins, but only 5 of the 8 pins are actually used. Two of those wires connect to the SAS (optional extras) module carrying Ethernet traffic via the X149*2B connector on the front driver left side. Two other wires from the ACC module carrying KL 15 power and ground connect to the Z44 (front power distribution box) module via the X148*1B connector on the front passenger right side. The fifth/last wire is connected to the radome heater.
From the factory, my car doesn't have any of those wires, so I will need to run two new wires from ACC to SAS for Ethernet through the driver side firewall. Also, I will need to run one wire from ACC to Z44 for KL 15 power through the passenger side firewall. The ground wire is connect to X148*1B connector which already has a ground wire on it from the factory.
I think I understand that part clearly. My confusion comes from which wiring harness actually is used. That Russian guy above tells to use 61129395453. However, according to
the catalog there is another wiring harness, 61126991536. The former (453) is labeled as front bumper wiring harness while the latter (536) is labeled as front end wiring harness. Based on my Google Images searches, it looks like 61126991536 is the actual correct wiring harness which are associated with X148*1B and X149*2B which are used to wire to the ACC module. 61129395453 looks like it is for the front bumper wiring which connects X148*2B connector to the front PDC sensors and fog lights on the bumper itself. However, I am not 100% certain...I'd like to have someone who's done this confirm my hunches
