Underhood Relay Query

[240 in OZ]

Hey All

In my eternal attempt for originality I am currently going over the engine bay wiring in my 09/71 240z. I have come across what I believe is a non-original relay (Bosch brand), but it seems to be wired in with original factory wiring (4 wires, shrink wrapped, factory style plugs).

It is located just ahead of the windshield washer bottle (keep in mind Im in the RHD part of the world), about midway down the inner fender. It is held in place with a single, large head, self-tapping screw.

The wiring seems factory and comes out of the harness. I suspect that the starter motor is wired to it.

My queries are:

1. Is this a relay and is it suppose to be there.

2. What does it do (which system is it for).

3. If it is suppose to be there, anybody able to let me know what the original unit should look like (description, pictures etc).

Thanks for any replies and information.

Regards

Joseph

If its any help my 73 doesn't have one. [And it's original again]!

I doubt it's original, Bosch sort of conjures up many odd PO fixes or add-ons. My bet is a relay added to the starting circuit.

I got to agree with Zedrally. The only things electrical in that side of the engine bay washer motor, engine bay lamp and either a Hitachi or Mitsubishi voltage regulator.

I went right through the electrical section of the AUS parts catalogue Zip for Bosch and no possibles, starting system relays are more the GM Ford thing me thinks.
