I picked up a 99 50 hp to replace the 40 hp Force on my pontoon today. Since the guy had swapped to a 90 merc on his pontoon, I got the motor, control cables, wiring harness, top mount remote tach and trim gauges and his engine stand.

So the tach connector was easy, I just need to figure out three other wire sets.

Blue circle - purple and white with blue tracer ( 2 pin connector)

Red circle - black, purple and gray wires

black circle - black purple and white with tan wires ( think these are the tilt gauge)

What about the other wires?

Me thinks I found the answer. Found a system check wiring harness diagram.
