Installation Instructions:
1. Find the location for the headlight relay under the hood between the headlights. The wiper door vacuum relay location is under the rear right-hand fender well or the left side of the firewall

Very well packaged. Did a complete vacuum test, ordered 2, both worked correctly. Ordered a lot from other vendors, those were all broken.This vendor is recommended.

Rebuilding headlight mechanisms on a 76 stingray. I rebuilt the actuators and replaced the actuator control valves. After that work, headlights work perfect. I purchased both the rebuild kit and the actuator valves from this company and everything arrived and worked great!

1 out of 2 worked, had to send one back due to malfunction; would not hold vacuum; since replaced it appears to be working properly; reason for giving it a 3-star; vette 74

Ended up ordering four to find two that actually worked. Sent the other two back.

Nice quality. One arrived with a faulty internal diaphragm so it won’t work the headlight. Hoping it’s just a one time issue!

Works slower than the original and it has no filter but it does not leak.
