IA 73-80 pulse delay conversion kits 2 left... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

*gmachinz* · 07-21-2016, 12:58 PM

I have 2 of these kits left at the moment-delays have been tested, includes a conversion harness and a diagram. Must use 78-up motor and motor linkage arm. $90 shipped each just like the last batch!
73-77 sorry.

bluex · 07-22-2016, 12:02 AM

Do you have a good delay module an switch for the 78 an up?

*gmachinz* · 07-22-2016, 02:18 AM

Yes I do....several in fact. $50 shipped if you'd like one!

covingtontn · 07-22-2016, 07:18 PM

John

Ok...PM coming....

covingtontn · 07-22-2016, 11:35 PM

Thanks G

If you come up with anything, please let me know. I would be happy to pay for one that would work on my 84 to 71 conversion.

Thanks
John

*gmachinz* · 07-22-2016, 08:37 PM

This is a stock 1977 2-speed wiper motor....you need to change this out for a 1978-up motor....and the wiper motor linkage arm is different too-they don't interchange so you need to use a 1978-up arm/nut as well due to the threaded shaft on the 1978-up motors being slightly bigger-the pivot ball which attaches to the linkage arm assembly is the same for all 1973-87 tho.

*gmachinz* · 07-22-2016, 08:40 PM

On the same 1977 GMC High Sierra truck, here is the 1978 motor and new harness leads all tested and ready to go! In my lot I also provide instructions for swapping out leads on the cab side of the fuse panel bulkhead connector too!

covingtontn · 07-22-2016, 10:04 PM

Hello G

Con this conversion be changed to work with a vehicle with updated steering column with the wipers on the column.
Thanks
John

*gmachinz* · 07-22-2016, 10:22 PM

Well the 84-up trucks have a different design where the stalk has the delay feature built in and there is a pulse delay circuit board integrated into the whole circuit too-not sure if it is even worth trying to make work ya know...? What year/type of wiper switch are you thinking about?

covingtontn · 07-22-2016, 10:40 PM

Hi
I have a 71 chevy truck and I wanted to put a 84 chevy column in it.
If you think this would work let me know.

Tiger Joe · 07-24-2016, 08:41 PM

Do you still have any of these left?

We have a 79 so I assume it would be a "plug and play" since it already has the correct motor.

Yes I do Joe! $50 to jenwood77@mchsi.com and I'll get one going your way!

Tiger Joe · 07-25-2016, 07:27 AM

I'll take one, sending PM

86454k30 · 07-25-2016, 11:31 PM

So I just bought a 77 K20, what do I need and how much to convert to delay?

*gmachinz* · 07-25-2016, 11:44 PM

The cost for a conversion kit is $90 shipped. You simply need to use a 1978-83 wiper motor and junkyard source the 78-up motor arm and nut too.

Gotcha, so no way around changing motor/linkage.

*gmachinz* · 07-26-2016, 12:05 AM

Right-it's a simple change tho. And, you'll need to enlarge the existing squarish hole in the dash where the stock wiper switch is located. You will need to drill 2 small holes to add the 78-up style delay switch-the 77 switch has mounts on top/bottom whereas the 78-83 switches are at opposite corners.

*gmachinz* · 07-26-2016, 10:22 PM

All pulse/delay kits are SOLD as of right now.....I'll put up a new listing when I have more available....thanks guys!

covingtontn · 08-09-2016, 01:50 AM

Hello
Did you every have any luck with the harness for 71 chevy to 84 chevy
wiper mod?
Thanks
John

*gmachinz* · 08-09-2016, 10:05 AM

Hey John-I haven't forgot about ya! I've just been super busy this last couple of weeks. Besides building harnesses I've been moving a lot of my NOS sheetmetal locally for guys too so it's been hectic....but a fun hectic. I'll keep ya posted-I have a local customer with a 67 C10 I may try to convert just to work out a harness for such a conversion.
