ok. the 3 wire pump uses 1 relay
2 wire pump uses 2 relays.
so. you are going from a 2 wire pump to a 3. so, this is easy.
because (with evinrude) they decided to only use a relay for "up" and direct wire for down as the weight
of the engine is then in a falling motion, and you dont need as much power to tilt down as you
do up (because its lifting the weight), therefor you only need ONE relay for the job.
depending on the type of relay used in your original 2 wire setup, i would say go buy a 12volt solenoid
as most relays use a normal spade conector (i dont trust them) where as the solenoid uses bolt conectors
but you best check that
View attachment 170370 the green wire is down, as it does not pass through the relay (solenoid)
black wire is earth and is on pin G
the red wire goes from the battery to pin 4 of the solenoid then to
your switch (red/white wire) (i added a 2nd switch to the engine )
the blue/white wire from the switch to pin 7 and blue/white wire from pin 6
to the up of the pump (blue wire)
Green/white wire from the switch goes to the terminal block then becomes the
solid green wire to the pump.
This is if they have kept the same wire color codes.
if you want to keep both relays let me know and i will draw up another cct for you using both the relays you have.
