Starter Relay Solenoid Question

They gave you the wrong part. (parts house morons)
That's a Ferd solinoid


OK.... I ordered a new relay and didnt get back what I expected... Well actually I did expect Crappy Tire to get it wrong so.............

Question is how do I replace this....



With this....



The new one has more posts and now Letters to indicate what goes where...

Can I use this or should I just wait and get one that's the same...

Thanks
Darcy
