Early 78-83 Intermittant wiper switch and relay
 

I originally picked this up hoping to find a way to make this work in my 77. I was actually lucky enough to find the UBER rare 77 only intermittant set up so I no longer need this. This is untested but came of a clean truck so there is no reason it shouldn't work. It includes the harness to the relay or whatever it is called. Price is $50 shipped within the USA.

Any chance you figured out how to wire this up in the 73-77 trucks ?

Re: Early 78-83 Intermittant wiper switch and relay
 

I never got that far. I do have a nice long length of the pig tail included if you want to give it a shot.

The wiper motor is different in the 73-77 trucks.

What does the 77 switch look like? have a pic?

Re: Early 78-83 Intermittant wiper switch and relay
 

It looks almost identical except it has textured black instead of clear lexan

Do you know if this switch can replace a bad switch in a non-intermittent '79?

That setup should be plug and play for 78-84

Hey 1774,
I'm interested in the relay but I'm waiting on you to send me some pics of some headlight bezels (I sent you a PM) so maybe we can work out a package deal. Please send some pics of the bezels. Thanks!

I got on my -77 an wiper motor from an -85 there I had to cut of the connection ball and weld it on the -85 wiper arm. I also got a wiper switch and the electronic box of an early -82-85 something and wired it all together. I can take pictures of the actual wires if you want to.

Re: Early 78-83 Intermittant wiper switch and relay
 

Thanks for the input. I would like to see pictures. If I understand correctly you put an 85 or so wiper motor on your 77 truck and you welded the part that connects to the wiper arm assembly onto the 85 motor? It that is correct sounds like a good way to do it.

Re: Early 78-83 Intermittant wiper switch and relay
 

Yes that is correct I had to weld that little ball from the 77 assembly on to the 85 wiper motor arm. They where different sizes, and it was easy to do that. I just hand filed the ball's weld off from the back of the 77 wiper motor arm.
I can take pictures of the wiring in a couple of days.
Sorry about my last post I was tired and I had to think how I did it+ english is my second language.

Re: Early 78-83 Intermittant wiper switch and relay
 

That is great info. I look forward to the pictures of the wiring. Thanks for taking the time to respond.

I got under the dash board tonight and realised years past and this is a good way to document how I did it.

And also you have to cut a little in the metal where the newer switch will go in.
With my switch on the signal I can just touch it lightly and the wipers will go ones even if the switch is not on, perfect if you get water from oncoming traffic after rain or at start up in the morning.

I do still have one. I will send you a PM with me email address and details.

Re: Early 78-83 Intermittant wiper switch and relay
 

Thanks Jeff. If the other switch you have comes with harness and everything as in your picture above I will take it. I sent you an email yesterday also.

Re: Early 78-83 Intermittant wiper switch and relay
 

1774btcrew, is there a part number on that switch pictured? i been trying to find one

Re: Early 78-83 Intermittant wiper switch and relay
 

I was finally able to do some checking and I do still have a pigtail harness with about 8" or so of wire. I didn't see a part number on it.
