Gear reduction starter connection

[Tronch]

I was reading the post of a couple of years but still I have sme concerns about the connection of this starter.

As I understand the wire comming from the battery has to be connected in the solenoid to the terminal with the big wire going to the old starter.

The white and red wire comming from the swith has to be extended and conected to the starter.

But my question is wich onw in wich terminal of the starter?

I think the big wire to the nut and the white/red to the faston treminal, but in my starter both arrives connected by a black wire???

Thanks

The new starter has it's own built in starter solenoid.

There are three ways to connect the new starter.

1- As it arrives, the car's original starter solenoid connections would remain as original, the heavy wire from the solenoid to old starter would be connected to the heavy terminal on the new starter. The short black wire on the new starter would remain in place.

This effectively puts the heavy contacts of the two starter solenoids in series. Push starter button, original solenoid sends current to the new starter, new starter solenoid energizes via the black wire, new solenoid closes & sends current to the starter.

2- The other option is to put both heavy wires on the same terminal of the original solenoid,(either terminal) one heavy wire to the battery, the other to the new starter solenoid large terminal. Remove the small black jumper on the new starter & move the small wire (white-red) on the original solenoid from it's original terminal to the small terminal on the new starter. This wire would need to be extended.

This method uses the original solenoid as a connection point only, & only the new starter solenoid operates the starter. Push starter button, new solenoid operates & sends current to the starter.

3- A third possibility would be as in #2 except to completely remove the old starter solenoid & install a longer battery to starter cable. The main harness feed wire (brown) from the battery terminal on the old solenoid would also need to be extended.

I prefer #2 since it keeps things more original than #3, but operationally removes the original solenoid from the circuit. One less thing to go wrong.

#1 has two starter solenoids that both need to be operating perfectly & reduces reliability. It does however, keep the parts & wiring as ALL original.

There is no real operational difference in the methods. Take your choice.

Method #3 was what I used, as my car suffers from a complete lack of originality...

Only picture I have of g/r starter was taken part-way through my oil cooler update.

Guys, thanks both for your explanation.
I have used option #2, to keep it more original.

It´s impresive how this starter can move the engine so easily
