Blue & Green Wire Out of Firewall block????

Getting ready to install a new painless wiring kit, right now I'm tracking down all the current wires.

There are two wires coming out of the fuseblock? (square plastic thingy on drivers side of firewall). Neither of them are hooked up to anything in this truck - (67 C10 LB, 2WD, Auto)

One is green.
One is blue.

Any ideas what they are for?

Has an aftermarket guage pod for amp, water, oil, none of these guages work in the cluster. Blinkers do not work either. (dash is not A 67 - LATER auto choke dash, no tach :~(

TIA!

I'm 99% sure that Blue is for the oil pressure sensor (for dummy light). Green is for the temp sensor (for dummy light).

That's for the 6-cylinder I don't know if it's diff't for the 327 V8 (I'm guessing the truck in his sig is the one he's asking for)

Thanks for quick replies - yes it's the truck in my sig (now with 383 for power) Is there a way to apply current to the wire or something and see if the light in the guage panel comes on?

Truck is original with a V8. Never had a six in it. If it will help I can run out to the shop and take a quick pic.

TIA!
