That's how the factory installed switches work.

Use the switch to trigger the relay to turn on a ground.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

So I took my '01 Boxster S to the local stealership yesterday to have my OBC enabled. I had already wired in a FWL switch to a couple of Bosch relays and tapped into my gauge cluster. By the way, to all who have or will do this hack, most other DIYs on this say you cannot get the lights to work on the switch itself because of the way thew switch is wired. The answer is a simple $5 relay. Use the switch to trigger the relay to turn on a ground. That's how the factory installed switches work. Anyways, my point was that the service manager (a very nice guy) had no idea of what I was speaking of. I may as well been speaking Martian. After several minutes of explanation, he called a service tech who said he didn't think it would work but he'd give it a try. The verdict: 15 min later my pretty littler grey car was telling me that it was 37 degrees F outside, my average speed was well below what I had assumed, and that when my foot is on the floor, I'm getting about 9 MPG. (about 23-24 otherwise) All in all, a pretty cool addition to the car. Total cost: about $100. Stealership charged me $50 for activation $30ish for FWL switch ( from Suncoast) $10 for 2 bosch mini SPDT relays (eBay) $4 for some diodes for the Shack (must use to keep relays from popping through speakers) $3 for the VW molex wire (from Suncoast)

Yeah, no matter how many times I reset my average speed, in about a week it is back at around 45 mph. Same with the average MPG, I reset it out on the highway and get around 28.5, but in a week it's back down around 24.5. We did a cruise last weekend on small 2 lane roads and has the CC set around 65 all day. It hovered around 31 MPG for most of the trip!
