couple questions;

1) yamaha B1 blaster the wiring harness coming down form handle bars has two plugs (one white one black) i need to find one of the white plugs (red/brow wires) form the engine side harness to the handle bar harness ....... what is the correct/proper name and where can I find one new or used.

2) 1997 yamaha wave venture 1100 engine wiring harness (going in B1) there is one big white four prong plug what is this supposed to connect to? I am guessing a instrument panel so I don't think I need to worry about plugin this up am I right?
