Default in need of a wiring diagram

Looks like Im picking up that Baja tomorrow

First thing I want to do is re wire the boat
it has all the original wiring from 1987 in it and a lot of the gauges done work, plus I want to add some stuff like electric fuel pump, ignition box and coil and some other stuff I have laying around the garage left over from some of my race cars,

Does anyone have a generic wiring diagram I would use to referance
boat has a single 454 Mag motor and Im going to be switching over to a Holley carb that I have as well, and probably a dual plane air gap intake that I have as well also
also what type of wiring and terminals would you recommend using and does anyone have a good source to locate them at a good price if you do would you mind sharing

thanks for any help you can lend
