Electrics: 140: missing unit/book discrepancy

[Triple-S]

One for the owner/driver of a 144GL rather than book facts.

My recently acquired 144GL was 95% through rebuild when the owner died. After initially fitting a battery to check circuits I noted a cluster of red wires adjacent the battery, with proper screw-on terminal ends, not conected to anything! I looked at the pic in Haynes which shows the injection fusebox fitted there. I then looked in that huge Volvo illustrated parts catalogue for its part number (to see if it is the same as that on my 164E, which is sited here) but find they depict it on the bulkhead very near the main fusebox. However, they only show it on an early 144GL whereas mine is one of the last made (main fuses down 'A'-post).

Question: is Haynes correct in stating injection fusebox is on relay rail on inner front n/s wing for my model. Is it that the parts book depicts typical arrangements, part numbers being their main criteria.

If my 'missing item' is something else ( havent yet looked for small fusebox near the bulkhead I must admit, and car is a long way from here!), can it be what the haynes wiring diagram shows as item 69, connector? The only physical connector (as opposed to an in-line thing) is what the parts book says is #347713-0 Junction Block, which they also show on the bulkhead (but I don't have one of these on my relay rail either!).

If my theories are correct I need the above junction block plus a plinth fusebox #688378-9: by any remote chance would anybody have these going spare!!! However, at this time, advice would be most appreciated. If anyone can do me a digital pic of their relay rail, showing how the missing bits should be mounted, I'd be very pleased.

My 1973 injection 145 had the injection fusebox behind the battery. What age of car have you got, D Jet, K Ket?

Our 145 1971 has this connector, it is a square solid piece of metal, covered with plastic, screwed onto and insulated from the inner wing (next to battery). One thick plus goes in from the battery, two come out and disappear into the wiring harness. I have had it disconnected, nothing worked on the car.
You can improvise something which would look very much like the real thing, wires are simply screwed onto the connector.

Is this possibly a diagnostic socket for use with the F.I.? I don't see one in either the 144 or 164 parts books but could be an item on the last cars only so not in either of my books.

Happy New Year!

Same as on both my 1974 model cars (142 & 144) and my 1972 142, but my 1969 145 doesn't have it.

It actually has 6 connection terminals, from memory ?

It's the main 12V power distribution "bus" for the car - actually a really handy feature, because you don't have to connect stuff back to the fusebox or to the battery terminals for add-ons like driving lights, electric fuel pumps, etc !

re DaveTrees advising on his cars, today I looked on a 68 144 and it didn't have this connector or fuse either.

Therefore I conclude the 144GL must be as the injection 164 of the period, in that it should have that conector there, but it MAY have the fuel pump fusebox adjacent, or it may be on the bulkhead somewhere, depending on the exact date of manufacture. If its anything like comparing my 1972 164E with a 1974 one, Mr Volvo was midway through a lot of changes about then, so the positioning of the bits may well differ - its just a matter of searching for them!

Any other ideas, and more helpfully a pic of the relay rail behind the battery of a '73 144GL, to confirm?
