I would like to ask you fine folks to please help me figure out a couple of wires. I am having trouble finding them on the wiring diagram. I am attaching pictures.

Picture 1:
Both of the wires have connectors.

Picture 2:
The pink wire comes out of the firewall using a grommet that looks like original factory wiring to me, a little bit above and to the right of the harness connector. But I suppose it could be an add-on for something.

Picture 3:
note 1 -- pink wire at the firewall
note 2 -- the connectors
note 3 -- the orange wire has a ragged end
note 4 -- they appear to be harnessed together at one point, now the wrapping is ragged

Picture 4:
Pink wire ends up at the fuse box, I am pointing to the pink wire with the red arrow.


The connector ends of both of these wires was sitting on top of the engine when I got the truck back from the mechanic who helped with engine installation. The mechanic gave me the helpful advise of don't worry about those wires, and hinted that the orange wire may have gone to the transmission to advance timing. The truck had a points distributor but has been upgraded to a used HEI and only one power wire goes to the distributor now. So, I don't know if these would have run to the old points distributor. I'm kind of thinking the pink wire may be power wire going to some accessory, and really don't know what to think of the orange wire. The heater blower motor has a purple wire going to it.

This is a 1969 Chevrolet CST/10 with 350 CU IN engine, Turbo 400 automatic transmission, factory air conditioning, no tachometer on the dash, and GM/Delco AM/FM/8-track.
