Bhai you should have gone to the service station first get it properly washed and then you will see what is the situation from the underside. Mukki is where the suspension is tightened to the body it that is not proper you car will have suspension issues and your tyres will be ruined very soon.
There is one layer of floor.
Playing with wiring is dangerous. Get the whole wiring sorted out. Remove any "nitro tape" joints and join the wires in a proper manner (search Google)
When ever I buy a car I get if serviced first and then change all the fluids, then check for wiring and suspension bushes.
Remember mere Bhai it is a Khyber not an FX. Fx is real simple to maintain and Khyber too if you know where to find parts.
Congratulations on the new car!
