I got a lot of useful info on this site, so decided to use it again, because I am a bit lost right now.
I own a B18FT engine, fitted into a renewed R5, now in the middle of resoldering all the wires to fit a smaller car.
I plan to use all the Volvo stuff, with electronic speedo.
Engine came from a beaten up 460 Turbo, made in 1994, had AC and ABS.
I bumped into a problem regarding OBD box. I can not find any good description of how components are fitted for box to work.
I could only use sockets 3 and 7 (only ones with wires fitted) and am now very much lost, because I took loom apart in intervals and now can't figure out where to wires go. Also some online manuals are totally confusing me.

So, top ones are probably ground and + from junction box, but from here on I am lost. On nr.3 the cable went into a cabin and I think goes to Jetronic, because I found a cable of the same colour. for the wire on socket 7 I've got no idea where it went before, I have a suspicion that it was directed to the speedo, but again, not certain

what are those cables separated by plugs? I saw they are test points for led lights, but does someone know where are they going? On my loom I only have one, brown-gray coloured wire, that goes to Jetronic computer and one of the same colour, that goes to EZ210. The one that goes to EZ was once cut off, I can not recall when and why, not even if that was my job

Because i have one spare of the same colour, is it possble that Jetronic and EZ share that same cable, so are connected through it? Are those the diagnostic test points?? Are those the wires for tests with LED? Where are they soldered to on the other end?
The spare loom, that i took for taking some broken connectors off, has two of such wires, one brown and one blue brown. I think that loom is older than mine.
thank you very much for help!!!
It is much appreciated!
