1977 engine bay wiring question

[Balmoral1958]

Have a '77 Bay Window. Was originally FI but PO removed it.

Now has dual Webers.

Wanted to confirm that if I use the B side of the double relay it should work.

Yes - will clean up the wires.

I will then install the fuel safety relay.

What's it going to do that your ignition switch won't?

running a low pressure pump to carbs -should be real simple.

That double relay will depend on a signal from the air box of the FI.-- If you hook that up it will need a source of power after cranking.---In that case, you might as well just put in a straight connection to the pump, or a generic relay to lower the load on the ignition switch.

I do not have the EFI connected. I just wanted to confirm the wiring to connect the double relay to the starter etc. so I can get it running. Then fit the fuel pump cut-off relay - or does the double relay cut-off fuel to the fuel pump if the engine stalls but the ignition is not cut off?

The double relay doesn't effect the starter or ignition circuit in any way, it gets signals from each of those to control functions of the FI but for carbs no part of it is needed. To run an electric fuel pump for carbs you will need something like this: http://vwparts.aircooled.net/Electric-Fuel-Pump-Relay-321-906-059C-p/321-906-059c.htm , carbs can't provide the signal your existing relay is looking for to turn on the pump.

The double relay can be used as a regular relay. I'd limit any connected load to maybe 5 amps.

Thanks - this great... so if I use the non-FI connections this will be the right connections to the starter , battery, fuel pump (I'm using the electric low pressure type) etc.

You can use the double relay socket to power the fuel pump and other stuff in the engine bay if you want.

The relay that BD mentions uses a signal from the #1 ignition circuit to know if the engine is running or not.

Update

It starts and runs using the “engine” side of the dual relay.

I have ordered the relay kit from Germansupply that has the fuel pump shutoff.

Thanks for the help!

OK - so trying to install the fuel safety relay below.
Where does the red/white stripe wire from the start motor attach ?

per the Bentley its 88d - do I need it ?

Thanks - it appears that I don't need that for my carburetor setup = its only need for the FI circuit.
