MF 290 Dashboard Lights & Re-wire

My MF 290 had a broken birds-nest of wires under the dashboard when I bought it, and I'm trying to get all the wiring sorted. I've got the warning-lights in the upper row on the dashboard for the temperature, charging and pressure sensors going, but there's three green unlabelled lights on the dashboard which I'm trying to work out what two of them are responsible for.
The green light on the right flashes when the indicators or hazard lights are enabled, but I haven't seen the other two come on for any cause, nor can I work out what they are supposed to represent.
I have a Shop manual for it but I haven't found any clues in there about the purposes of those particular lights (extract attached).
Any help would be appreciated.

Welcome to the Forums.

Looking at the parts books I can see on the AGCO site we use here; I see 6 options for the 290 model. Making a quick look at them, I didn't see an arrangement like the one in your picture. Does your 290 have a warning light on both fenders? Is it set up so you can select one indicator or the other as a turn signal? If so, the indicators might be for the left and right lights when used as turn indicators. Depending on how they are controlled and wired it is possible that one indicator is for both lights as hazard warning and then the other two work with just the left or right light as selected.

Do you have the correct Operator's Manual for your 290? That might give you info about the function of those lights.
 
Thanks Jim. You are correct in that I might not have the correct manual - the one I have is the only one I had found online at this time. My specific model is 290 8SW (SN. A114075) with Multipower transmission, manufactured in France (see photo). I'm not sure what year that means it was manufactured.
The tractor does have warning/indicator lights mounted on the fenders (which have had a rough life), but it has an aftermarket (Rollmasta) cab and fenders installed, so things have likely been re-jigged at some point. Your suggestion of the lights on the dash being for indicating left or right does make sense - I'll have a look over the next couple of days if there's multiple wires going to the same light (indicating they should be going to separate dash-lights).
I've watched many videos of re-wiring the dashboard instruments for various Massey tractors, and although many other Massey tractor models include those three lights on the dash, none of the videos I've found have re-wired those three lights or even mentioned what the lights on the dash were representative of, hence asking here.
