Bosch starter motor wiring ID

[Porkchop]

Hi chaps, I've just replaced the Bosch starter motor in my 1984 240 Estate with a reconditioned Bosch from a 1988 model 240. Apart from the starter being a pain in the arse to get out and reinstall, the wiring connections are different on the replacement starter. Previously I had two male spade connectors on the back of the solenoid, two joined blue/yellow wires went to the lower spade and two joined brown wires to the upper(smaller) spade.

The replacement unit has three full-sized connectors arranged differently (one to the engine side and two to the outer side, this is the older one: https://imgbox.com/D6GGSORL

And this is the new later model Bosch: https://imgbox.com/f216kfxQ

Any info would be great, I find auto electrics a bit daunting!
