I came across an original 65 windshield washer kit (pics below) that has the motor, bag, tubes, nozzles, and switch. There are some instructions (from 7-64) included, but before I get into it, I wanted to gage how extensive this kit install really is.
Aside from putting in all the components from the kit such as the motor and bracket (both where sheet metal dimples indicate), is the switch that's supplied with the kit basically a swap-out with my existing wiper switch? The kit is for a single speed washer which is what I have in my 64 1/2 (single speed motor).

Since you have single speed, should all be plug-n-play.
-
If you have purchased the kit to add washers to the car then the assumption would be that the car has single speed wipers without washers.
If this is the case then your existing wiper switch will be a 5 pin and therefore it doesn't have the pull out washer function
The new switch with the kit should be 7 pin and have the pull out washer function
Your existing harness plug will plug straight back in leaving 2 pins left unused
One of these pins takes the wire to the pump and the other is connected a powered socket
The longer black wire with the white stripe has a moulded boot on one end this plugs into the pump
The other end into the switch
The short white wire plugs int the switch and then to a power source

Very neat kit! Thanks for the pictures. ;)
I'm guessing finding the power feed wire on a car would be an indication of a post-factory washer kit install? Or did the factory do it the same way?

My car does not have an existing hole for the wire that runs from the pump and through the firewall. What size should the hole be at the firewall?
There is a rubber grommet on the pump wire that looks to plug into the hole at the firewall, and from the inside of the car (plug bigger on side inside car versus firewall side).
I look to have a dimple on the firewall above the wire harness that enters above the break line junction.

Measure the retaining portion of the grommet first - twice.

I also don't have an existing hole for the black wire retainer that would plug into the inner apron just up from the pump, to gather the hoses and wire off the pump. I have a dimple (white dot in picture) up and to the left of the large round hole beside the pump.
What size hole is drilled for the wire retainers?
-
The Osborn 64 1/2 electrical assembly manual shows the install in more detail and provides the hole diameter size for the strap retainer for the hoses coming off the pump, .247-.251 diameter hole. I take this to mean a 1/4 drill bit will provide the right size hole?
There was no listing for the correct diameter for the hole to feed the pump wire through the firewall and to the switch. Anyone with an original washer system know what this hole diameter is?
-
Here is a closer look at the wire and attached rubber grommet. The hole could be a little smaller than the grommet where it meets the flat face end that would be on the inside of the car up against the inside firewall. The width of the retaining portion of the grommet looks to be 1/2 inch. Since it's rubber, I'm guessing a slightly smaller hole would be best?
Anyone had an opportunity to measure their hole opening for this wire and grommet?
-
Measure the retaining portion of the grommet first - twice. There are known differences between factory installed items and NOS.

Referencing the picture I posted, there is the large flat portion, then an indention separating the flat part of the grommet from the tapered portion. The widest part of the tapered portion (part that would be inside the engine bay) is 1/2 inch. I'm guessing the hole size would be slightly smaller since the grommet is rubber and can compress some through the hole.
That said, I'm surprised how hard it is the get the information on the size of the hole from the factory. It seems easy enough to get the hole size for GT fog lights (guess this is a more popular add on) but not for single speed washer pumps. I'd like to be precise versus guessing at the hole size.
-
Can anyone measure the hole size at the firewall for a single speed windshield washer?
The size is probably different for a two-speed since there are more wires and the grommet is probably larger (don't know for sure).

The pumps are all the same for '65 and early '66, which means the same single wire is used for single or dual speed wipers.

The pumps are all the same for '65 and early '66, which means the same single wire is used for single or dual speed wipers.
Based on this info, then it looks like there is another active post in this section looking for the same information, "firewall hole locations and sizes", http://www.concoursmustang.com/forum/index.php?topic=8224.0 (http://www.concoursmustang.com/forum/index.php?topic=8224.0)
If so, then the hole size for early '66 and my '64 1/2 would be the same (i.e., same grommet/plug for the firewall used for single and dual speed washers), both with a single wire that goes through the firewall but splits off into two wires to the switch and one down to the fuse box.
Any info on the size of the hole for the grommet would be appreciated.

Both cars in the garage didn't have washer setups, so can't help, sorry.
I guess you've combed over the installation instructions and no mention of this?
-
Charles, yes, I checked the instruction sheet very carefully; shows hole location but no mention of size. Unfortunately the instructions in the kit consist only of the diagram for install and not written instructions like with some kits. The Osborn electrical assembly manual lacks and written details too. I also checked the other assembly manuals, all references/previous posts on this site and searched the web for other install queries...no luck on the size of the hole for the grommet at the firewall.

I'll be making a trip to the salvage yard in the next week
so I can check the hole size for you and report back.

So with trial and error, looks like the hole size for the grommet at the firewall should be 7/16. I drilled 3/8 first and then tried feeding the wire through the hole. The feed wire from the switch to the pump goes through the firewall from the inside first as the largest part of the grommet is on the inside.
What I found was the flat connector that connects at the pump and has to feed through the firewall from the inside is 3/8 inch and will not slip past a 3/8 inch hole (it is hard rubber and does not flex). If you drill a 1/2 inch hole, the flat connector to the pump goes through, the grommet fits too but is a little loose (have to use some strip caulk on inside flat part of the grommet to secure). So using a 7/16th hole would be the right size, large enough to allow the flat connector to the pump to feed through the hole but small enough for the rubber grommet to be able to "grab".
