i am restoring a 1995 vip boat. it had a 1993 model mercury quicksilver 3000 throttle with the trailer button on the bottom right corner. the trim up button didnt work it would only raise with the trailer button. it was broke so i replaced it with a newer throttle quicksilver 3000 made in the year 2000. it does not have the trailer button on it. so what im asking is how can i wire it up so i can use the trim buttn on the handel for up and down. from throttle there is three wires red green/white and light blue. form the boat harness there are 4 wires gren purple red an blue. any info would be great thanks.
