M76b wire? sensors? relays?

The electricals are a mess on this car as there was an
alpine alarm system fitted and there are about a zillion
cables everywhere. I noticed a few loose cables, including
one that has the peugeot wire code M76B. What is this?
It is loose in the trunk, close to the fuel pump. Fuel pumps
seem to run. The main fuel pump definitely
run but it's hard to say with the in tank one...

I suspected the tachymetric relay first, but I bypassed it
and it doesn't change a thing. If I disconnect the cold
start injector (Bob bruce suggested I'm only getting gas
through the cold start injector) the car will not start at all.
It may be that the fuel injectors are not receiving any pulse
as suggested by Joe or maybe the fuel pressure is too low,
due to the in tank pump.

Joe suggests sensors. The airflow meter has a good connection,
but then again, disconnected or not, the engine starts and
stall the same... The coolant temp, i dont know, could be... where
is this? The oil level sensor was disconnected (i think this is
when John G was playing with the alternator) and also there is
under the car, under the transmission to be precise, a loose wire.
There seems to be a sensor on the transmission without wire, but
could be something else. What is that sensor?

Last, there are two relays under the dash (not the tachymetric
relay), one green made in Italy, with 6 connectors and inside
has resistors, two of which look burnt, transistors and a relay,
and one black, bigger, made in France, Klaxon. Klaxon in french
means horn, and it is probably related to that, but why so many
wires... So, what are these two relays?
