Hello,

Can anyone help me identify the following four items from under the hood of my 1971 Demon?

#1 is a connector from a wiring harness located near the washer reservoir

#2 is a metal clip that I found in my driveway

#3 is located on the passenger side of the firewall

#4 is located on top of the engine

Thanks for any help,
Michael Anzalone

#1 is a connector from a wiring harness located near the washer reservoir
looks like brake warning light connector, proportioning valve

#2 is a metal clip that I found in my driveway
lower steering column bearing retainer clip

#3 is located on the passenger side of the firewall
emission device

#4 is located on top of the engine
emission device
 
#3 and 4 are two halves of one windshield washer pump, broken in half. The item in 4 is the actual pump that used to be mounted onto the base in photo 3. Remove them both until you find a replacement. The clip may be from the torsion bar frame socket, but that is just a guess. The item in photo 1 looks like the electrical connector to the brake proportioning sensor, but it could be something else.

Thank you for the reply. I'll see if I can find a place for #1 to connect, and I think that I have found a diagram for the retainer clip. Any idea where I can find more information on the emission devices? (Another user suggested that #3 & #4 are part of a windshield wiper pump, but my car has the rubber bulb on the floor, and no aftermarket switch inside)

Thank you for the reply.

#3 does look like a pump to me, but my car has the rubber bulb on the floor for the windshield washer, and no trace of a washer switch inside. (I am the second owner of the car, and see no evidence that an electric pump was ever installed)

Thanks again,
Michael
 
#1 looks like an oil pressure sender plug.
#2 does look like and T bar retainer clip that goes at the back end of the bar in the socket on the crossmember. (If that is a T bar clip you want that back in there before it gets driven or the bar can jump out of the socket when you hit the brakes)
The stabilizer rod may hold it, but that would freak me out if I found that in the driveway.

3&4 look like smog equip vacuum controls to me.
 
Update:

#1 did indeed connect to the proportioning valve
#2 did belong to the steering column

#3 & #4 are still unclear; here are some more photos...thanks again for all replies!

the white part of #3 is a vacuum switch it turn on one of the turn signals to show that the engine is under a lot of power. the switch has a habit of leaking vacuum. the metal part might be a control switch. so the two systems dont interfer with each other. the black part looks like something is missing. my idea DONT try to use it. if you want the car to look stock just make it look like its hooked up but plug the vacc hoses so you will not have a vacc leak.
