I need some help identifying the purpose of the two wires located just forward of the driver near the brake reservoir. The color of two wires terminated together are brown/white and the single wire is brown. This 914 is a 1971 edition . Any ideas?

I’m thinking they may be to the brake switch on the MC.

The black protected covered wires behind the brake overflow tube caries wires down to the brake master cylinder so it still is a mystery. I think in 1970 the 914 had a fuel pump in the fuel tank area just below the mystery wires . Maybe they might have used the same harness and used them for a fuel pump?

The only brown/white i recall in the front trunk are for the horn(s).

No idea why that would terminate there though.

What's the story with the car? Is this a restoration? Has the harness been replaced? Has the harness been rewrapped?

The two wires to the MC brake switch are brown and brown/white but they're obviously not long enough.

The colors and location make me think they are for a brake reservoir cap with a low level sensor.

Touch them together and see if the brake light flashes.

Here are mine. 1972. Connected to nothing. Must have been an option mine didn’t get.

I have owned the car since High School 1975. Took it apart for restoration in 1995 for restoration but life and family took priority and now its time to finish it. The harness was removed and rewrapped so probably they belong in the cab and would end around the fuse block. Mystery solved once I know for sure where they terminate. Thanks guys!

I’ve had this car since 1982, and never messed with this area. I didn’t even know they were there until I looked.

What is the width of the spade terminals? quarter inch or half that.
I was thinking the door switch
No way for a reservoir cap with a low level sensor or a gas heater!

Both the same size, about 1/4”

I don't think i'm right but the only other thing that would have been optional in there - the wiper delay relay?

I think EJM is correct. At one point Porsche was experimenting with a low fluid indicator on the brake circuit. There was a cap the had leads which would set the brake light on the dash when the fluid was low. I remember seeing a post about this. My 72 has these wires in the same spot…not terminated.

The intermittent wiper relay wire is brown/black and if i remember correctly was not part of the harness on early cars.

Damn, now I want to do it. (IMG:style_emoticons/default/sad.gif) I found one that mentioned a year that is close 1985. Could someone with a 85 911 go eyeball your brake fluid reservoir cap and see if they are the same? Or if someone knows if the 914 and the 911 in 85 share the same size cap. Thanks
