    Low profile 90º OBD2 and DB15 connectors

    I've managed to find sources for connectors that may be of interest to those who find the Nanocom supplied cables a bit awkward for in-car instrument usage.

    The first is a low profile 90º db15 backshell.

    These are stocked by RS Components/Allied Electronics. The RS part number is 2509191199. They are $7.96+gst each with a minimum order of 2.

    The second is a low profile 90º OBD-II plug. These are sold by Fes-Auto in the US and work out at about $20AU shipped for one. I don't have the connector with me but they have a tiny footprint compared with the standard item. The cable can exit either left or right of the plug, and this makes it easy to route the cable in a way that doesn't encroach on the footwell.

    To give you an idea this is a pic from the vendors website showing the connector as part of a cable assembly.

    hope this is of use to someone.

    cheers

    Bit of a dodgy pic but this gives you an idea of how the right angle db15 backshell lines up with the nanocom evo.

    Great bit of detective work Paul. I've been wondering about finding a solution to mounting my Nanocom in a way that doesn't impede in driving.

    They look like the ones

    I was going to use the one I bought with the Nanocom One I owned at the time, but made the very silly mistake of following the wiring pairs listed on the Nanocom FAQ without double checking against the patch cable I'd bought. The One uses an RJ45/network connector rather than DB15 and of course the cable I had used different pairs. Hence the rather hacked at appearance of the backshell That is moot given I now have the Evo....

    This is how the assembled connector sits in a D2 using a more flexible cable than supplied:



    BBS have gone overkill on the EVO connector cable which is a "good thing" for something that is designed to be repeatedly unplugged. I'd use a lighter, more flexible cable for instrument panel usage. You should be able to route it up beside the centre console without too much drama.

    cheers

    Finished cable

    I finally finished putting together a short cable with the r-a connectors, and some jaycar sensor wire. The length is per gavinwibrow's request as he is mounting his Nanocom in front of the D2 coin tray, which seems to be a reasonably good place to house the Evo.

    Offtrack, can we please have the part numbers for the various parts, and a wiring diagram...?
    Thanks

    Hmm Paul

    You may have an after hours job soldering cables if you are not careful

    That looks a pretty neat job

    See the first post in this thread.

    The plug for the nanocom is a basic db15 solder pin job that can be picked up from Jaycar. The wire I used is 4-core sensor wire, although I'd probably use mini "star quad" microphone cable like the mogami w2893 if I was going to buy cable again.

    http://www.mogamicable.com/category/...crophone/quad/

    The star quad is design to repeated movement and flexing as a microphone cable, so should be sturdy enough for a short instrument cable.

    OBD -> DB15
    4 -> 8 - Black
    5 -> 15 - Brown
    7 -> 4 K-line - White
    16 -> 14 Power - Blue

    The colours refer to the cores in the wire I used. Black/Brown are ground wires and are connected on the OBD plug PCB, so it doesn't mater which way round you hook those up.

    The linked OBD plug has a very weirdly laid out PCB board, so the wire layout don't match the pins. I basically id'd the correct pins then traced back to the position on the pcb I need to hook the wire up to.

    cheers
    Paul
