Hydraulic trim and tilt wiring

[Double Trouble]

I have a replacement hydraulic ram which i am installing, however i have a problem.

1. 2000 model assembly 6H1-17, two wires a green and blue.

2. My motor asembly 6H1-10, three wires black, green and blue.

Ive got power but the 2 wire pump needs to be earthed for it to work.

Can i somehow earth the 2 wire pump or do i need to change the trim relays to a later model type?
Thanks

Will have to replace trim relay to a 2 wire relay to match trim/tilt unit you have.
