you will need the wiring from the hull oil tank to the engine and the trim/alarm harness from the engine to the console as well as the 10 pin main harness.

are you going to use a side mount box or the 704 binnicle type box?

the 703 sidemount has the 10 pin harness in it. the 704 does not.

the pre 95 harness's wont fit post 95 stuff without an adapter, the exception is the main 10 pin harness, it has not changed.
