OK, back at home. The diagram labeled "Additional current flow diagram California, Type 914, Model 75" shows a blue/yellow wire. It goes from the catalyst relay, to the catalyst mileage counter, to the CAT light in the dash.

It also shows a black/yellow wire that goes to the EGR light from the EGR counter.

And it shows a red/white wire that goes to both of those lights, providing power to them. (The other wires apparently provide the ground for the light to turn it on.)

So there you go, your wires are indeed for the EGR and CAT lights. Just as Ed and Jeff were saying.
