delay wipers

[mdm365]

I have asked this before although it has been some time . I was told some of these non delay are plug and play of course mine is not.​

With that said I have got this switch and delay module

Mine is like this one

I know it does not fit were the original one is with out doing some cutting I can deal with that some how.

Two things I don't have is a wiring diagram for the 77 and one for the 80's model , Can some one help out with this... Maybe some one has done this??

I do know I do have return to park type wipers also the delay module has letters a follows..A-Gray wire B-Black with blue stripe C-Black with white stripe D-Light blue E-black F-dark blue.Not sure what does what

Any input will help!!!

Thanks mike

ttt...i have the same wiper switch setup as the top pic, its out of an 83 or 84 2wd pu, i want to put it in my 80 k5. does anyone have any info on this swap?

i know the headlight and wiper switch is physically in a slightly different location, but will the switch itself interchange in the diff model year positions?

after installing the intermittent switch, will the regular switch plug, just simply plug into the pigtail? or do i need to pull the plug from the truck that originally had the intermittent wipers(i still have the parts truck the intermittent switch came out of) and cut the plug off of my k5 and swap plugs following a wiring diagram? will the regular switch have all the connections needed for the intermittent switch?

On yours I do believe it's plug and play , Just unplug the original switch and plug your harness in the back of the module you should be good to go.

I think I could get mine working if someone had wire diagrams for me hint hint anyone

Bringing this back up in case it was figured out. Or does anyone have something to add? I'm trying to replace the switch and delay box in my '77 with the switch and updated delay box from an '82. It would be very simple if GM kept the wire colors the same, but they did not

Update. I found that I have a wiring diagram book that covers the '79 Chevrolet passenger cars. The '79 Camaro wire colors and plug are the same as what's found in my '77 K5. The '79 Corvette uses the same wire colors and plug as the switch and module I have from an '82 Suburban. After comparing diagrams I have been able to figure out what wire hooks to what. But with the new switch, I have high speed only and when the washer is pushed, the pump runs, but not the wipers. It acts the same with or without the delay module hooked up. What's wrong?

 

[USSkoval]

Update again. There seems to be a difference in how the wiper motors themselves operate. On the '77, the switch grounds the low AND high circuit to operate the low speed. It only grounds the high circuit to run high speed. The later style switch only grounds the low circuit to run low speed, which will not engage the low speed on the '77 motor. It does operate in high. The newer switch also has a separate wire to park the motor. Tomorrow I will get a new wiper motor for a later year truck and see how that goes. The stock motor does not park on it's own anyway, like it's supposed to.

I see this thread came back..

I got this e-mail form a guy here some time ago that I will share with you..His name is Mike also,Don't rember his screen name

This is what I did with my set up.

1)Delay switch P/N 14028808
2)Delay control P/N 15598419
3)Wiper motor ’89 K5
4)Washer motor ’89 K5

The ’89 wiper motor does not have an integrated washer motor or pump. The washer pump is a separate unit. This is important as it is part of the delay circuit and must be close to factory specs to operate. It also gives you the large washer bottle that is really helpful when you need to clean the windshield a lot.

I pulled the connectors for my set up out of a junk K5. The connectors required are the two pin wiper park connector, three pin wiper speed connector, the washer motor and bottle with connector and the connector that plugs into the back of the delay module. I also pulled the firewall bulkhead connector to use a couple of pins. Napa and pep girls sell replacement pins for all of these connectors. There are a mix of PAK-CON, PAK-CON HD and type 56 contacts. You could re-use a lot of your existing stuff and splice the wires to make things easier.

All of the connectors are labeled with “A”, “B”, “C”, etc for contact names. The firewall connector uses numerical contact names such as “91”, 92”, “93, etc. Starting from the connector that plugs into the delay module the wiring is as follows.

Delay “A” is a gray wire that goes to the dash lights. It can be connected to the terminal on the fuse block labeled “light”. This turns the bulb in the delay switch on and off and gives you the dimming function.

Delay “B” is a black with dark blue stripe wire that goes through circuit “97” and then to contact “B” of the two pin park connector on the wiper motor.

Delay “C” is a black with a white stripe wire that goes through circuit “91” and then to contact “A” of the two pin park connector on the wiper motor and to contact “B” on the three pin wiper speed control connector. The wire on the engine side is grey in color.

Delay “D” is a light blue wire that goes through circuit “92” and then to contact “A” of the three pin speed control on the wiper motor. The wire is purple on the engine side.

Delay “E” is a black wire that goes to the ground node “150”

Delay “F” is a dark blue wire that goes though circuit “94” and then to the pink wire on the washer pump.

The white wire on the washer pump goes to switched power for the wipers in the fuse block.

Contact “C” of the three pin wiper speed control connector goes to the switched power for the wipers through circuit “93”.

The only feed through on the firewall connector that was not in place was circuit “97”. Adding that circuit required pulling the fuse block while the other dash wiring required removing the instrument cluster to get access to the wiring. The engine side wiring was easy to get at. You could splice most of these wires and save your self a lot of grief but I felt that doing it per factory would make life easier long term. An ohm meter/test light would be very helpful to ensure that the wiring is correct. The delay module is reliable when wired correctly but will act as a fuse if it is wired incorrectly.

To get the delay wiper switch to fit you will need to grind/file/trim the opening in the metal behind the plastic bezel. Take your time and do a little at a time and it will all fit like factory.

I can scan or fax you the factory wiring schematics if you need them. Let me know if my description doesn’t make sense.

I never got the diagram from him and It came a little late for me. I wanted to get the wipers done and not spend a lot of time trouble shooting all the wires so I went and got this click here

It came with some good instructions and works just fine if you don't care about having something mounted in the cab.Did not have to use a new motor or switch.

Hope this helps

Good idea to upgrade to the newer motors if doing so....just get the washer bottle too. Wiper motor mounted washers suck.

Yep, that's what I've figured out so far. I got the new wiper motor today, the style with the built in pump, but I'll get the newer style connectors to go with it since they are considerably different than the '77 connectors. I'll just have to run the extra black/blue wire from the switch to the park connector through an existing hole in the firewall.
