Can tell u some common places
Oil psi sender - Put a tee down were the turbo lube line/oem low oil psi sender light is.
h2o temp - Upper left hand side not right of motor while facing the front of the car is a single wire for the high temp idiot light that is a good place. But, I tried a tee so I could keep the high temp idiot light but the sender was not in the "flow/stream" of h2o to be accurate so I just left the idiot sender out.
Another place is the lower intake manifold below and slightly to the right of the throttle body a single green or gr w/yl stripe wire goes to it that is your fan delay relay sender. Some folks remove it and slap the h20 sender in there.
Good luck
