Seat heaters

Has anyone added seat heaters to their boxster via one of the kits from an online retailer? I am eyeing one that is pretty cheap and comes with the buttons. I was thinking about getting one and installing an original heater switch (I have the dummy switch right now). I have to remove my driver's side seat cover anyways since I have a rip and want to get it reupholstered. I know this topic has been beat to death, but I am not talking about th $1000 option or replacing with different seats, just buying the kit and installing it under the original leather and wiring it to where the heater switch should be.

Thanks,

The ones I am looking at are Dorman 628-040 Universal Seat Heater Kit from Amazon. I have tried to post the link a couple of times and it will not let me.

Thanks,

Thanks, Starter. I figured it was that I had no posted enough or something. That is the one I am looking at, if anyone has any experience with it or something similar.

I posted on my website a few days ago about how I think you would wire aftermarket seat heaters to OEM switches without doing the full OEM install like Dennis Vogel's DIY. Basically, you just wire aftermarket heaters to the OEM switches and relays, and do the wiring yourself. The only part I am not sure about is the compatibility of the relays and the two stage heater functions (high, low, off), with whatever aftermarket heater elements you choose to use.

I have not tested it, but it was a project I had been very curious about for several years, and I was already reviewing the wiring diagrams for a different project so I took a few minutes to work on the heated seats. Again, no guarantees it would work, but take a look, it might be helpful.

Rick,
Thanks, I will take a look. I was looking at the reviews for the one I posted and it "seems" rather straight forward. I would think it would not be "that" difficult, but who knows. I will take a look at your site and see what I can do in the next couple of months.

I've done the "Dennis Vogel Install" and I think Rick's suggested procedure will work.

I recently bought a 2005 Mercedes C230 that had a torn seat cushion. When the upholsterer repaired the cushion, he inadvertently damaged the seat heating element. He replaced it with an aftermarket pad and I wired it into the system in a manner similar to the one suggested by Rick. The Mercedes has 3 heat levels and they all work fine,

You can check this thread on Rennlist for more information on seat upgrades: https://rennlist.com/forums/boxster-and-boxster-s-986-forum/915206-upgrading-two-way-power-seats.html

Unfortunately, the document is too big to post here.

Thanks,
