Ford / Mazda 3.0 V6 wiring problems

I bought a 4 door courier and sorted a lot of the wiring out but still have some issues with the dash gauges but their wires are on their places I think lol, and there a quite a few wires left in the engine bay that dont have locations
1. 2 blue and yellow from the fuel pump relay that goes through the meter fuse on fuse box and the tach, they carry 10v for some reason
2. A thin blue/ red wire that goes to the cluster on pin 2
3. a thin red / white, which i think might be reverse lights
4. lights and high beams work not the parks
5. got the hazards working but dont know if the same relay should work the turn signals as well because they dont work either.

on the cluster
the oil and charge lights dont come on on ign and the clock, tack temp and fuel dont work either. everything is wired in their places tested the wires from point to point and they are fine. but im sure im missing something somewhere.
the high beam light works and the hazard lights come on. oh and illumination lights and thats about it.

is there anyone that might be able to assist me or can send me in a direction for a wiring diagram online or something please..


any help will be appreciated

forgot some pics of the wreck
