Im a newbi here so firstly id like to say hello to all

I am hoping somebody may be able to offer some sound advice
regarding a problem with a new starter motor?
I have a golf gti mk 2 16v big bumper 1991 H registration and have owned her for 3 years now,
it's not my first golf as i've had 2 others previous to this but in all that time i've never had to change
a starter motor and im now really stuck.
I've removed the old starter motor with out too much hassle and managed to purchase a new one.
Problem is on the old one I had a live wire and an earth wire which were both seperately connected
to the motor via they're own female clip/spade connectors.
The new starter motor however has only one spade connection and neither the original live/earth
wire clips can connect to it, im v.confused as im told the new motor is the correct one to have...
I've considered stripping the wires and fitting a standard female spade connector to
the live wire which could then be connected to the new motor but this still leaves the earth wire.
Could this possibly be wired into a standard ring connector and then be connected to the casing
with the main battery cable and earth perhaps?
Is this safe, can anybody help me out here?
Thanks in advance
