Now I'm homebound , i got the idea to build an new dash.
In my workshop i do have an bendable LCD (shockproof) what will fit nicely in the old dash.
so I'm occupied by writing and rewriting software, based on the OBD elm-scan-software.
At this point I'm a bit stuck, on how to implant this on the ecu of my rig.
I time ago, i did ask on the forum, about the two yellow connectors just in front (a bit below) of the cooling liquid expansion tank.
I got as an answer that those connectors are a kind of pre OBD 1/2, and called BRDII i believe.

I would like to use the output info from those connectors in to my new dash.
But before inventing the wheel again, i will hope that some of you will know the pin-out of those two connectors.
It will save me a lot of (investigation)time.
