1969 windshield washer pump motor
I'm trying to piece together a working windshield washer motor and pump from the different pieces I have. The po had a long hood so he had a newer style washer motor. I have a rebuilt 69 windshield washer motor, a (I believe) 68 3 port washer pump. I dont have the water pump anti-drip valve for the 69.
My questions are:
How do the wires plug into the washer pump. Its a two wire connector blue and yellow and can plug in either way. Looking at it going left to right is it blue/yellow or yellow/blue? Or does it matter?
If I get ahold of a 69 water pump anti-drip valve can I attach it to the 68 washer pump? I looked on the upper right where I believe it connects and dont see any mounts or holes for it to screw on. If not can I run a tee off the three ports to go to headlights?
Thanks everyone
Pat

I do not think that it matters on how the connector goes on. Your connect is made to be installed one way due to he the slots that they cut out of the brown plastic . Those slots usually provide an area to allow the terminal to go on because it has a raised tab made into it so it makes the installation of the plastic connector idiot proof. Your terminals look like they are bent and do not look like they have the raised tabs on them.
I believe the yellow and dark blue wire are actually supposed to have the bullet terminal made onto them and they are not in a connector...they are separate.
If you are trying to plumb in the washers for your headlights. You need to only splice into two of the hoses and not all three.

Thanks DUB and Alan. The wiring harness is a new replacement from Lectric lmtd but that brown terminal connection matches the same as illustrated in doc rebuilds chart. The two terminals on the washer pump......I dont know if they are bent down or are supposed to be straight up? The black rectangular flap underneath/ behind the two tabs moves like a door so I'm not sure how its supposed to be. Looking at Alan's 68 it looks like he has the two wires coming in from the side as bullet connectors into some sort of rectangular box. Alan are you able to remove that connection and let me know if the terminals are supposed to come straight up and if there is a door flap with them?
I guess I wont be able to run the anti drip solenoid with this set up. I'll have to keep a lookout for a 69 washer motor.

The picture below is of an original 1969 wiper motor, pump and headlamp washer extension jumper wires... The 1969 washer pump should have the bullet connectors. This design was used until 1975 when the pump changed. The 68-69 washer pump was the same (both using the bullet connectors) and both having a three port white washer pump as shown in the lower picture.
The wires can be plugged into the pump in either fashion but the correct manner is illustrated in Alan's picture with the blue wire towards the passenger side. The wires control an electromagnet, so all it requires is power and ground from either side of the circuit.

So if the blue/yellow wires come into the washer pump from the ignition/engine harness, where/how does the two bullet connectors from the anti-drip solenoid connect to? Also would I be able to connect the anti-drip solenoid to 68 washer pump?
Maj75, are these the jumpers wires your talking about?

This is the stock harness. .
This is the by-pass jumper.

Maybe someone with a 70-72 can help with this but since I'm not building numbers correct 69 wouldn't it be easier and cheaper to just use a 5 port washer pump from a 70-72? Do those extra two ports run to the headlights and negate the whole anti drip solenoid from the 69 or is there some extra solenoid down by the headlights on the 70-72. TRying to find a washer hose diagram for a 70.

Will the connector you have in your first post plug into the washer pump? If it won't you could un-pin the terminals and just plug them up to your pump. The pump you have is an aftermarket pump but the terminals if unpinned will plug onto the terminals on the pump.
If you are wanting to run the headlamp washers and don't want to put the pump and solenoid on your motor you could just place a T in the output hose to the wiper arms, the pumps have enough push to pump water to both the headlamp washer and the headlamp squirt nozzle.

The connector in my wiring harness does plug into the washer. If i run the headlight washers off a tee will they drain out the reservoir? I thought that was the whole concept behind the anti-drip solenoid? Or was it just to act as seperate spray for windshield and headlights? Thanks again for all the help. This has been great learning more and more about these cars.

This post is gold for me. I have been doing lots of work to my car, but one of the two things that has bothered me the most is that I never could figure out where the blue and yellow engine harness plug went to. I also could not figure out why my washer pump wasn't pumping (go figure). I couldn't see the bottom of the anti drip solenoid to see the connector that it was supposed to go to. I still have a few things to do before I power up the car again, but I bet the pump works now.
This forum has always been great. Thanks to Alan 71 as always for the treasure trove of pics and thanks to Willcox as well. I will be buying my new wiper motor parts from you!

So I have a different issue. My '69 had no washer pump on the wiper motor, nothing. One of the past owners jury rigged a washer pump to the firewall and routed the hoses to it. I installed a new washer pump and removed the jury rigged items. I thought the washer pump was driven by the wiper motor and the washer would work. But after reading this blog, I see I am mistaken. So the wiper motor has connectors for the bullet connectors as willcox has shown. I do not have headlight washers and the connectors willcox has shown are for a by pass from the headlamp washer motor. Are there different connectors? Or do I just snip off the ends and connect to the harness?

Yes, I resolved my issue. I removed the jury rigged pump and routed the houses to it and used bullet connectors for the wires and it works fine. I did some research on youtube and this has helped with a few issues such as the wiper plenium door not opening and the wiper situation. I found a man called corvette ben there who has really interesting videos on cars he rebuilds that you might enjoy.

So I just installed a new washer pump on my 69. Has the headlight function also. When I tested it, the pump starts pumping even without pressing the switch on the dash and continues without stopping. It almost sounds like it clicks itself on, does the full wheel rotation and seems to click back on. The whole time the wipers are moving I can see through the white housing the piston keeps pumping. Can this still be an electrical or mechanical issue? when I installed the pump to the wiper shaft, I inserted the shaft into the slot on the back of the w/p. Is that the correct way?
