i was just hoping someone could say its eg the red wire and i could put my multimeter on the becm and the other on the obd to see if i had a connection, if it was only that easy
Pin 8 of connector C1279 99 on C255 prior. Pink/red to pin 7 of C0040 99 on, C231 prior. Pin 17 of C1279 99 on, C255 prior. Light Green/red to pin 15 C0040 99 on, C231 prior.
C1279/C255 are connector to BECM. C0040/C231 are OBDII connector.
BECM pin out and connector locations. http://www.nanocom-diagnostics.com/downloads/1556252923.pdf
Hope this helps but learning yourself will make things easier for you.

Obd connection problems on old cars are usually the joints at the obd plug

:drum::drum:
so how easy is it to drop connector out so you can test both front and rear of each line on obd connector socket ,,, I presume its a line end running off the main loom to where its positioned ????? so logically thinking the whole bracket etc comes away so for access to do any soldering on rear of socket ????? so how to do it would be helpful !!!!!!! regards MOZZ

Just remove the panel from below the glove box that the OBDII plug is in. Then you can get at the back of the connector. Maybe a couple of screws and a couple of push in plastic fasteners can't remember but not difficult to do.

Plastic covers when removed expose four large Philips screws
Think you may find that is for the cover under the steering wheel.

Ok remove plastic covers and remove phillips screws hows that.
I only know that off the top of my head because I dropped my socket when I was fitting my new'ish steering wheel and had to remove the one on the drivers side.
and getting you back for the earth strap/ safety cable dig.

Yeah but the OBDII socket is under the passenger side. I would not have a dig at you Alan mate. Honest i wouldn't.

I know it is Tony, do you mean the n/s and o/s panels don't have the same fittings? Why am I not surprised.

History repeats especially on R R's. Now my second 2.5 DSE, first was a 96 RHD in Cardiff, sold to come to France in 2018, now my second RR, is a LHD RED 97, different issues. Currently the Nanocom (just bought) wont connect fully to the OBD, from past threads a common fault, probably rusty OBD, very awkward to get to, would have been better placed under the bonnet, any tips on how to get at it for either replacement or refresh. Did 4 fuses in trying to connect the Nanocom as there is no switch, and unplugging on the Nanocom it self from the cable blows the number 33 fuse. Lesson; Always keep the Nanocom cable plugged in! I'm thinking of running an extension cable into the glovebox for ease of access as my guess is I'll need lots of access to it over the coming years. Over the last year spent 4000Euros on various bits and pieces, bought it for 2300euros in Niort 2019, mostly Gboxauto changed and other things, but must get the OBD working. The Turner diagnostics replacement ECU runs very well much improved performance. LOVELY NEW NANOCOM not much use without a functioning OBD ****
