I have a switch and delay module from a mid 70's truck. I also have the motor from a '71 truck. I want to put this in a '65 that has an original 2 speed motor. Can someone tell me if I have all i need to do this? Do I need to swap motors? How does it "plug" into the existing wiring harness? A diagram would be very helpful.
Since it hasn't rained here in several months, I am hopefull this will bring it on.(Probably right in the middle of the conversion..of course)

 

I saw where a guy in the 48-60 forum (12-04-05) (krautwolf) "is his screen name", did a upgrade using a Ranger wiper system. Granted his upgrade was on a 59 not a 65, so could be less modifications, I recommned doing a previous search to find out more glues to your upgrade; ( Intermittent wiper mod's). I didn't even know a two speed was an option back in 65? I will evently upgrade to a better wiper system myself.

 

What I had to do was use the bracket and wiper motor pivot arm from the 66 on the mid 70's wiper motor but it was all bolt in then the delay box plugged right in. I had single speed wiper motor so that is why I changed my wiper motor.

 

merc460, how did you interface to the truck wiring harness? I think that is my biggest concern. The module and switch plug into the motor, but it has to also tie into the truck harness. Anyone?

 

the mid 70's version just connect between the stock switch and the motor. pull the plug off the stock switch and plug it into the delay box. the other end goes to the new delay switch. the setup will work with your stock motor.

 

Prostock: I did this upgrade to my '66 and it took me about 3 hours, going slow. I used the parts from a '76 F-150, so that should help guide you in the parts list. The best way to do this upgrade, is to harvest the following parts from the donor truck:
Wiper motor
Harness between motor and delay module
Harness between delay module and wiper switch
Delay module
Switch
Optionally, take the following:
2-wire harness between switch and washer "bottle"
Washer bottle (fits the '65/'66 inner fender really well)

When you take out the wires, don't cut any, except the hot wire and the wire to the to the washer motor. (I think those are the ones you cut, anyway.) You should have to cut only 2 wires, if I remember right.
Installation is a bolt up procedure.
To install:
Replace the '60's motor with the '70s, using the '60s motor mount bracket AND the '60s bellcrank.
Set the original wiring harness for the wiper motor up out of the way; I used a plastic tie for that. I think the wires to the original switch are separate, not combined in a plug. You may be able to use one of them for a power lead to the new harness. Tie them up out of the way, regardless to avoid problems with short circuits.
Plug up the wiring harnesses, and wire up the hot wire to a connector on the fuse panel if you didn't use a hot wire from the original switch. (Be sure to include a fuse in the circuit.) Be sure to complete the circuit with the ground wire as well.
Remove the original wiper switch, and measure the length of the stem. Cut the stem on the 70's switch to the same length. You may find it easier to install the switch first, then cut the stem.
Replace the original wiper switch with the later one, and use the orignal **** on it.
It looks original, and works great!

 

Pro stock, banjopicker66 explanied way better than I could he is right on the money.
I did use a 80 and up delay box so I only had to hook up one power wire for both the washer and wipers.

 

Thanks guys! Looks like I have everything but the harness between the motor and delay module...off to the boneyard! I already have the later style washer bottle, but I think I'll keep it wired to the "mystery" button above the key switch...keeps it old school, and that's cool.

 

I picked up a switch and modual on ebay then sweat the wiring harness only to figure out that the wiring on my 66 stock two speed moter had the same colors on the wiring...it was all WAY simpler than I expected,and it almost makes me glad when it rains now...hope yours turns out so easy also! It also seems that there is a tech article here on FTE..

 

The single speed wiper motor bell crank is required. The two speed Bosch American bell crank will not work. I wrote a technical article on this site for this swap. It is literally as easy as BP stated and really a nice feature.

 

William you have thrown me a curve. My truck has an original 2-speed motor. I'm assuming that bellcrank will work? Can't see why it wouldn't. I hope to be able to go the same route as seetwisted, and use my stock 2-speed motor.

 

It has to do with the slot in the crank being set at a different angle. You have to use the original to be able to park the wipers correctly.

when I got it all hooked up and tried it, the wipers parked in the wrong spot.So I unhooked the wiper arms and adjusted them down...it took a few times but they stop close to where they're supposed to be.Did I just get lucky and "Micky's" ears are showing? I wouldn't be surprised if it's not the way it's supposed to be,but I still really like the upgrade.
