Fuse tap...
Illuminated star...
I own a Mercedes-Benz C300 2015 and I ordered the star from ebay and could not make it work. I followed the guide step by step on https://mbworld.org/how-tos/a/merced...ed-star-384223. do you think by fuse tapping it will work? can you advise?
Thanks
Let me know if you have any questions.
LED illuminated star
wire harness assembly
Remove the star counter clockwise from the grill
Locate your engine fuse box in you driver side
Remove the plastic cover and expose the fusebox
Use a Torx screwdriver and remove the 2 screws and remove the top cover. Use a pry tool to carefully pry back side of the fuse/relay module
Life up the edge of the fuse/relay module. There is sufficient wire underneath so you can pull the entire module out and set it aside.
-Mark center of the top side edge and place another marker 1 inch down. Drill a 3/4" hole<br/><br/>-Route your red wire that comes with the kit through hole in grommet
In the back of the fuse/relay module, locate the S8 connector and connect the red wire to position 8 of the connector
Reinstall the fuse/relay module back to the box and install a 5A fuse into position F123 (B)
Remove plastic rivets (1) that secure the radiator support panel
Remove plastic rivets (2)
Remove plastic rivets (3)
-Route the cable towards to the center of the radiator<br/><br/>-Route the ground cable towards to the passenger side
Connect ground wire to ground terminal (passenger side)
Connect the star wiring harness
Reassemble in reverse order.
My thought is that the positive electrode connects to the positive end of the battery and the negative to the negative end of the battery and then the signal wire taps into the fuse 108 or 110 for the headlights so that the star comes on only when the headlights are on and not as DRL's, but again this is just my inference and conclusion from this diagram. Any good electrical engineers out there who can help out, would be highly appreciated

+ Electrode = goes to battery + positive
- Electrode = goes to battery - negative OR any properly grounded screw in engine bay.
ACC = tap a fuse that only has power when the cars accessories have power OR when the engine is running. Your choice. (this is only to switch your star on/off)
You may need this.
As a test (before installing) you could connect the - and + wires to the battery, and then touch the ACC wire to + positive battery terminal to see if star turns on/off.

Also, i think the main battery on a 2015 c300 is in the rear i think and only the aux battery is in the front so is it ok to connect it to the front battery?
Just waiting for someone to confirm that I am in the right direction and I will go to town with this diy. The seller, unfortunately retains from giving any instructions 😔

Worked perfectly on my C Class. Just follow the instructions and you're all set.

I have a query regarding how to connect the wire to pin 8 of the S8 connector. When I stick it in it keeps falling off.
Thanks in advance ...
