JB4 help

[E31BMW]

Hey,

Asking for a little help here with my JB4. I have had several JB4's and install them myself, usually just stage 1 with a Rev 4 bluetooth unit. I bought my latest JB4 from a user here and it came a bit wonky.

The Rev 3 unit has a modification: couple of leads coming out of it, assume one is ground and the other is positive. I think that the later Rev 3 unit come without a ground wire? Not sure how to connect this Rev 3 unit.

Also, the enclosure is missing a bolt, which I am trying find where to purchase and the actual motherboard was unplugged from the cable supply (good thing I opened the enclosure prior to install. Not sure where to obtain these 2 bolts that connect and hold this in place.

Just looking to get some insight on my situation and install, thank you for your help in advance.

Cut the black (ground) wire off and tape the end if you leave a bit exposed. Splice the red wire to any of the 5v red wires in the main harness.

Any sort of computer store/fys/microcenter will have those small screws. For the enclosure bolt. Check home depot. I think they have some that are in the tray cabinets in the middle of the isle. You'll have to search though but I saw some at my home depot.
