Took out rally dash, bezel and gauges, from 1971 Demon 340. It did not have a supporting metal piece on top of the plastic that I have on my 1968 Barracuda. Should it have one? Or did they do away with that in the 70's? Second, I converted a 1972 non-rallye dash harness from a Dart to fit the 1971 Demon. It has a weird (to me) wiper connector. The female connector is different from 1971 wiper switch. 71 is first photo. 72 is second. What year(s) switch do I need? Only 72, or are there other years that will fit? Does anyone have one that is willing to sell? Thanks for reading.

Yes the 71 rally should have the metal reinforcement. My 71 Demon does. If you have a 71 wiper switch for the dash and it appears you have both 71 and 72 connector, why not de-pin the 72 harness and install the terminals in the respective correct points on the 71 connectors to use with the 71 switch. If you don’t already have a 71 switch might be easier to locate a 72 switch. Just my thought.

I believe the differences you are seeing on the harness plugs, is one is for the 2 speed wiper switch and the other is 3 speed/variable wiper w/ push in washer function. they are different. :)

Like Fgill stated switches are different. You need a switch to match wiper motor. Then use correct harness for switch.
 
Thanks for replies. So the 72 harness wiper switch connection is for 3 speed switch. The female terminal at 11 o'clock is way out there and is vertical instead of horizontal. Stared at it for 20 minutes before it sank in. Fgill, Is the switch on the left in your photos the 3 way switch? Still doesn't look like it would fit my second photo (72 harness). Dubob I like your suggestion...but how do I de-pin the wiper connection? Trying to avoid cutting the 5 wires and splicing obviously. Do you mean pull the 5 wires out the connector and push the plastic housing out the back? Aren't there problems getting it out on the bulkhead side? Can you give me more details, thanks. Wiper motor should be 2-speed since that would fit the harness I am replacing, but I will check. How do you visually tell the differences in wiper motors? 3 speed vs. 2 speed. I assume it would be a third or fourth electrical terminal on the motor. Always listen to experience. Thanks
 
To unpin the connector spades from the plastic plug is super easy. Please follow my directions. Take a small flat blade jewelers screwdriver and fit it into the plastic connector from the front side where i marked with an arrow. If you have to file the screwdriver flatter to make it a depinning tool then so be it. I have one i made into one of these.

The spade connector has a small tang or tab that sticks up against a small ledge inside the connector that locks it in place so the spade wont pull out of the back of the connector during normal use and vibration. The modified screwdriver is used to push the tab down to clear this ledge so you can pull the spade out of the back of the plug. You then bend the tab back up before repinning it into the connector. Make sure you orient the spade correctly going back in so it will lock in place. The small slot in the front side of the connector is for a depinning tool.

1. Push and hold wire forward in connector. This helps to release and push down the tang or tab on the female spade.

2. With wire held pushed forward insert depinning tool in small slot from the front side of connector, as shown in my pic, and use it to push lock tang or tab down towards spade connector.

3. While holding depinning tool down against lock tang or tab, pull wire back out of connector.

If you have a spare junk connector, recommend you practice on this one first and familiarize yourself with the way these lock in place. I may need to make a tutorial on how to remove these female and the male spades.

I recommend when you have them out prior to repinning in your other connector to clean them with a brass wire brush and some CLR, the slightly recrimp the female so it plugs into the switch tightly again.

Hope this helps
Matt

Heres pic of mine, 3 spd. Notice how the motor lays."flat". On 2 spd the motor "sticks out" for most years.

Nice leece neville motor Steve. I could never find parts to rebuild mine. I ended up restoring a prestolite vspeed for it. Would you be interestedin a spare 67 leece neville vspeed for parts? Everythin was cleaned and sandblasted, some stuff primed and painted.

The 3 speed switch is the one on the left in my pic. It has the resistor piggy backed on top which operates/regulates the variable speed control feature.
This 3 speed switch will fit your connector shown in your 2nd pic, however, your connector has an extra connector/plug at the 6 o'clock position. I cannot recall (been 20yrs) why some have that and others do not or if its even used or not as all of my 3 spd switches dont have that terminal.

I do know there is more than one type of 3 speed switch, some are 3 speed w/ variable. some are actual 3 speed only. all 3 speeds switches have the push to wash feature & therefore must use the electric washer pump located in the fluid bottle. Manual washer pump (on the floor board, use only the 2 speed switch & wiper motor.)

Also to note, the 3 speed motor uses a very slightly different bellcrank that connects to the wiper transmission arms. Again, i do not know why the change, but I do know they are slightly different.
So - in order to use a 3 speed switch/convert to 3spd, you will need at minimum; the 3 speed switch, 3 spd wiper motor and 3 spd bellcrank. To use the push to wash feature, you will need the proper washer bottle w/ electric pump and engine bay lead wire to said pump. All in all, easier to simply convert your harness to take the 2 spd switch and keep your existing 2spd set up, but its a common upgrade to swap in the 3 spd /power washer stuff.

For reference, the pic below has both style of mopar wiper motors.
the 2 spd unit is on the left, 3 speed on the right. (not my pic)
I hope this makes sense..lol

Hey Matt I might be interested, shoot me pics n price.
Thanks

Can do tomorrow. Going with a 2 speed in my kids car, and my prestolite V speed is restored, and has spare parts for it. No need to hold onto this stuff if you can use it. I did keep the wiring plug off it.
 
Thanks Guys. Valuable info. Great detailed instructions. Will do the unpin work this week. I have a box of old Mopar wire/connectors for practice.
 
Let me know how well the depinning procedure i detailed in my post worked out for you. It works well for me.
 
Steve, heres leece neville parts. Old mud dauber nest on aluminum housing is free of charge lol. Its a complete wiper motor minus plastic wiring plug. Housing was sandblasted and painted silver, motor housing was sandblasted and painted black. Send a PM if interested. I have no idea what to ask for it, make me a decent offer.

Matt, Your instructions were great. Did some practice on spare connectors laying around. Grinded down a cheapee Chinese screwdriver as per instructions. Before I do wiper connection, what is CLR? Contact cleaner? What product should I buy? Thanks again
 
all 3 speeds switches have the push to wash feature & therefore must use the electric washer pump located in the fluid bottle. Manual washer pump (on the floor board, use only the 2 speed switch & wiper motor.)

Not exactly. Push to wash feature in my 67 is jumpered to the wiper park circuit ( simply a scotch lock connector at bulkhead ). One push equals one sweep intermittent operation. Foot pump washer added. This doesn't work for those late model switches that self rotate to low speed when pushed.
 
Glad my instructions worked for you. Sometimes translating what you mean in words is hard. Pictures are sometimes easier.

CLR is a product you can get at lowes or home depot in the household cleaners aisle. Stands for Calcium, lime, rust. An alternate is Noxon. These products along with a small steel wire brush and you can polish up the contacts before repinning them. Then you dunk the ends in water to rinse them off, and dry with a paper towel and a little compressed air.

To clean, I hold the connector and its attaching wire down against a piece of plywood , dip the wire brush in CLR or noxon and scrub the connector, then flip it over and scrub the other side.

After cleaning, bend the tang back out to allow it to lock into the connector. You can also take a small pair of plyers and squeeze the female spade slightly to make it to where it grips the male spade tightly again when plugged in.

Male spades are easier to clean and use a small pair of electronics needle nose plyers to remove. Hard to describe, you put the plyers in on the front of the connector and squeeze. This pulls its tang inward, then you pull the wire and connector out of the back of the plug. After cleaning bend its tang back out and reinsert the connector.

When i repin connectors i slways pull back on the wire a little to make sure its locked into the plug.
 
The wiper connection was truly simple to do and that CLR cleaning solution worked great. Cleaned up the old 2 speed switch great. Saved me much time and money. Can I use this cleaner on the bulkhead and fuse box connections? Can't think of why I couldn't, but I wanted to check first. The 72 harness I am using is in great shape but those two areas should be cleaner. Thanks.
