Detroit Speed Selecta-Speed Wiper Kit Model # 12160
This kit offers a modern solution for cleaning the windshield in inclimate weather. It has 5 delay speeds, low and high. It also has an optional washer kit that can be installed. The billet switch will replace the factory switch and you can push it in for the washer and turn it clockwise in steps for each delay from slow to faster to low speed to high speed.
This will be a big improvement over the OEM wiper kit. I did have a major concern that was not addressed with the online description of this product. I am also in the middle of the install, so I do not have all the answers yet and hope to provide those answers soon.
The concern is that I have a 1970 El Camino with recessed wipers. This kit is designed for the 1970-1972 models with sweep gauge and non-recessed wipers. So, I may lose the recessed feature, not sure yet. I think many people may be in this position and think this product will not work in their car. I did see other discussions where this kit should work with the recessed wipers. Time will tell.
When I started the project, I planned for 4 hours. As my wife likes to point out, most of my projects take twice as long as I plan and she was certainly right on this one. The major obstacle I faced was with the switch replacement. The mounting poles for the switch are built into the lower dash assembly and these are plastic. 50 year old plastic, that is. Of course, I noticed that one pole was broken, one was already repaired with glue and in the process of removing the screws I managed to break all 3 mounting poles that hold the screws. So, much of this install time so far has been spent on my back under the dash trying to fabricate a solution so I can mount a new switch.
Here is a photo tutorial:
Selecta Speed Windshield Washer Upgrade-1 Here is a look at the OEM wiper motor with a recently updated OEM-style washer pump. These take up a bit of space on the firewall.
Selecta Speed Windshield Washer Upgrade-2 The new wiper motor was quick to install. The OEM-style washer pump will not work with this kit. If you want a washer pump, Detroit Speed makes you buy it as an additional part.
Selecta Speed Windshield Washer Upgrade-4 Here is the OEM switch. You push it in for washer and slide it to the right for low then high speed. No delay options and my motor performs pretty jaggedly and slow. The entire black piece in the middle will be pulled out and the new one will be installed from behind.
Selecta Speed Windshield Washer Upgrade-5 Here is a view of the mounting poles. There are three. And then there is a metal grounding strap that is mounted to the two right poles. The top right and bottom right poles are broken. You can see the top left pole is cracked and I managed to break it all the way when working on the fabrication.
Selecta Speed Windshield Washer Upgrade-7 Here is the OEM switch and hardware. I decided to use two small metal plates to mount to the dash, then the screws will mount into the white spacers. In this photo I started by super gluing the spacers to the metal brackets.
Selecta Speed Windshield Washer Upgrade-8 Then I used a small strip of 5-min pipe compound to reinforce the spacer to the bracket.
Selecta Speed Windshield Washer Upgrade-9 This is my first attempt on the mounts. I had several problems. 1. The spacing was not quite right for the screws to line up. 2. The metal brackets were too close to each other and the new switch did not seat flush against the dash. So, when you view it from the front side, there is an obvious gap. You can see that I reinforced the upper left pole with pipe compound.
Selecta Speed Windshield Washer Upgrade-10 This is my second attempt to mount the brackets. Spacing was better but the brackets still created a gap. It was a very small distance I needed to go so I pulled out the dremel and grinded some metal to make the fit just right.
Selecta Speed Windshield Washer Upgrade-11 All the grinding is done. The switch now has a very good seat. The two right poles lined up well, but I was off on the upper left pole by 1/8” so I had to use pipe compound to keep that piece in place. I also had to push the grounding plate to the side. The space I was working in was too tight to get all these pieces lined up so I just moved them. The grounding strap is still connected to the original ground location and functions as it should.
Selecta Speed Windshield Washer Upgrade-13 The wiring comes in a plastic loom, but the wiper wires and washer pump wires are in two different looms and require two holes through the firewall. I wanted to avoid this and it seemed like the wires were long enough to reach the washer pump. So, I cut the washer wires, fed them through the main loom with 1 1/8” grommet (needed for passing the big connector) and I was good to go.
