installed heated seats, with OEM switches Options

[Batman722]

after reading azian's post a few years ago I've wanted to install heated seats. I know others have done it but I never liked the aftermarket switch they came with and wanted to do things just a little different than everyone else had done and I wanted mine to be more OEM. I kept putting it off and finally my incredible woman was nice enough to get me a set of the OEM switches as an early Christmas present so I bought the seat heaters and decided to stop talking about it and do it.

first start with these


^^ same as the overseas celica switches and available in the US (from a Sienna)

get the connectors - important ! they are left and right specific !



panel from a vert



another pic (from the back)



and then the fun stuff. I got my hands on a Sienna EWD and my multimeter here's what the pins do



1 = illumination +
2 = HI setting
3 = LO setting
4 = POWER
5 = illumination -
6 = GROUND

I happen to have a few old interior harnesses to de-pin this is why I keep so much junk



then I pinned the new connectors





put together shot



and now add these


^^ seat heaters from ebay



and a shot of the ebay seat heater switch and what do the wires do ? break out the multimeter and BAM, here's what they do.

RED = power
BLACK = ground
WHITE = Hi setting
GREEN = Lo setting

and some part #s

switches


connectors


panel


I cut off the ebay heater switches, connected the wires to the OEM switches, wired the illumination wires to the lighter ring, and put the heaters in the seats. I re-checked everything and plugged everything in and BAM, heated seats with OEM switches.

quick phone pic of the switches (I put my alarm LED in the blank spot)



they work perfect.
The switches illuminate with the lights and HI and LO light up when they're pressed. The seats heat up well and this is gonna make me happy on those cold mornings.

I'll take and post up more pics tonight.

Nice! I've got a question about heated seats. I've got cloth seats in my car, (I know some of you are already like uh oh...) and I would love to swap them out for leather but I don't have the money for that. I wouldn't think it would be a good idea to put seat heaters in a cloth seat but one of my friend's parents has them from the factory in a Saturn Vue. I know, Saturn... Gay. But they put seat heaters in cloth seats. So is that even doable? I'd like to have heated seats but I'm not brave enough without confirmation from somebody OTHER than Saturn.

My girlfriend has a Jetta with heated cloth seats - I absolutely don't think you need to have leather to install these. They shouldn't ever get hot enough to be a hazard. I'll keep you updated on that one though, as I also plan to do this same mod! But I was just gonna hit a junk yard to find some switches that didn't look quite so "Made in China" as the eBay switches do.
