Title: How to put delay wipers in your C and B Body
Post by: Steve on October 08, 2009, 03:43:43 PM
Installing Delay wipers on a B and C Body.  On a budget
 
It's not rocket science. . . But it will take some electrical ability to figure the wiring.  Here's why.
 
You need to find a delay wiper switch that will fit your dash and keep it stock looking.  Example in Polaraco, I used one from an Aspen.  (Left to right slider)  StitcherBobit modified the activation shaft so it would go straight out the dash.  The switch was ultimately a screw in.
 
You can use a delay wiper motor from just about any late 70's Mopar.  Diplomat/5th Ave, Aspem/Volare, included.  They are all bolt in and the shaft is the same size as the C's.  However, if scrounging, make sure before you sneak it out of the yard.
 
It's best if you get the timer bob and plug from under the dash too.  Any harness sockets are a BIG plus.
 
If you can grab a set of wires and timer all from the same car, you need a wiring diagram for that car. 
 
The motor will bolt and mechanically connect right up.  The wipers will park properly, but you may have to adjust the arms slightly.
 
You will need some sort of a connecter for a 5th wire through the firewall if you decide to use the existing wiper wiring.  Delay wipers are 5 wire and the C & B is a 4 wire.
 
When working on your wiring, you may want to bench test it.  The wiper switch MUST be grounded for it to work.  Also remember to ground the motor to the same source.  There is at least 2 wires which will require grounding between the switch and the timer.
 
This is a good start for you.  I used a Wiper Motor, harness, and switch I got from Butch, HemiFury.  He sent me the whole harness.  But I still had to mate the connections at the bulkhead because the colors changed.  As I mentioned above, Bob modified my handle so it would go through the 72 Polara dash.    I love the feature
 
As we all know. . .  Delay wipers are great.  Well worth the time and effort.

I have all the parts to do my wagon....eventually...I robbed most of mine out of M-bodies and dodge ram trucks from the late 80's.

Just curious, is there a major difference that makes this not work for A bodies?

It's been a long time since I did a wiper motor on an A.  Is it the same motor as a C?

Not sure myself.  
 
So, your mention of B&C didn't exclude A, you just don't know for sure?

That is correct.  If it uses the same motor, then chances are, yes.  I thought it was a smaller motor on the A's

The wiper motor mounting to the firewall is the same for all cars as far as I can tell up to at least the say the Dippy's,  FWD cars I don't know.   Same 3-bolt pattern for all A-B-C & E's.  The Aspen was the same pattern.

2 & 3 speed motors are the same bolt pattern & the delay motor looks just like a 2-speed ( if in fact it maybe is just that with a delay switch )  So bolting up isn't an issue.  Only issue would be the wiper transmission to the motors hookup where there is some differences.    Early cars had solid brass bushings & clips & the later cars had the Nylon snap-in bushings ( the ones that fall apart! ) but some mixing & matching should take care of that.  I think all you'd need to do is swap the motor arm to transmission for your style & that's it.
