EG5.

I have 5 wires to fuel pump (located under rear seat)

Yellow / White Stripe
Black / White Stripe
Green / Red Stripe
Black
Yellow / Green Stripe.

I understand Yellow/Green should have 12V+ , but is it only at ignition point 2 (starter being at 3). correct?

Black I figure is pump earth, but what are the other 3 for please?

(I'm probing to see if Main Relay or Immobiliser System is broken)

Thanks for help!
