Printer Friendly Forum Posts - acura rsx heated seats wiring diagram

Whats up everyone,

i have a 1995 honda civic si & i just purchased a pair of 02-04 Acura RSX seats.. that come with side air bags and heated seats... Now the harness is still connected and i have enough play with the wires..

EDIT:
i was just searching through the site and found the diagram for the heated seats..

https://www.the12volt.com/installbay/downloads.asp

In the picture it shows it going to indicator's & lights

those are not necessary in my case, since these seats are only on and off and have no adjustable setting. But from the looks if it the process will will be

fuse - relay - switch - seats

is this correct??

Thanks guys, any help would be greatly appreciated.

I've said this so many times I ought to start asking for commission from the company. Or the12volt could send an e-mail encouraging them to advertise on this site(hint, hint) and so forth, but...

ALLDATA is a great resource in my experience. You can buy a single vehicle one-year subscription for $14-$17 and (if you get one for an RSX of those years) it should have the exact connector pinout diagram for the heated seats, and complete circuit information for them also.

All you need to do is ground the 2 black wires. One from each seat. Apply power to the GREEN/ red of one seat, and GREEN/ orange of the other seat. Considering the probable current draw, you should use a switch to trigger a relay to power these wires.

mint,sounds good, now is there a specific type of relay i should purchase?, or it doesn't matter?..

just to clarify i can use one relay for both seats right?.. because i will have two switches one for each seat..

Thanks for your help guys i appreciate it

chriswallace187, i know about alldata.. and if you saw my post i had the link on where to get the diagram for the heated seats. i just wanted to clarify the procedure..

But thanks for recommending it.

I would hope that you would use one switch and relay per seat. Your passenger may not want a heated seat everytime you do. A standard Bosch/Now Tyco 20/30 amp automotive relay should do the trick.
Here you go

hahaha yeah man i get what your saying, well i need this part asap so i can go to a local store and pick one up.. the only auto relay they have is 40amp

im assuming this is also suitable?

& should i add a fuse? or is that not necessary?? because the diagram shows a 20amp fuse connected.

Also when i get my power, does it matter where i splice into to get it?

I am debating on connecting up the side air bag, but im not sure if its worth cutting into my SRS system to add it in.. i dont want to damage the system ;s..

Thanks guys i really appreciate it

That relay will be fine. Any time you add anything to a vehicle, if it requires connection to a power source, you should fuse that wire at the point of connection to the power source. You should get power for the relays at the battery, using a 20 amp fuse and at least a 14 Ga. wire. The single wire can provide power to both relays. The hot wire that goes to the switches, should get it's power from a source that is only hot when the key is on or in the accesory position.

alright cool, i will go pick up the relays.. but when your telling me that when im connecting it to a power source..i should use 14g from the battery to a 20amp fuse to the relays..

When your saying i need a hot wire that goes to the switches, that is only hot when the key is in the ignition or in the accessory position. thats not necessary right?

cant i just use the hot from the battery directly to the switch?.. so i can still have the ability to turn the seats on whether or not the key is in the ignition?

Yes put the fuse at the battery. The switched source is not necessary, but if you supply it with constant power, the first time you forget to turn the switch off, you will awake to a dead battery.

oh ok i get what you mean now, thanks.

well i have purchased the relays, switch, fuse holder, and wiring.. now its time to wire this baby up and see how it goes.. i will keep you guys up to date

Thanks for the input

hmm i ran into a problem..

after i connect the fuse to the + of the battery i then run the 14g wire to my relays where i branch off and make two connections for both relays.. These connections then go to terminal 30 ?

85 - grounded
86 - would be when the key is in the on position
87 - switch on
87a - switch off

is this right? or am i doing something wrong

Thanks guys

anyoneeeeeeeeeee????

ahhhh

30 battery 85 ground 86 to the switch Other leg of switch to a switched 12 volt source. 87 to the seat.

hahah you beat me to the chase man

i went and figured it out

just like you stated above

Battery: + of the battery went to the one end of the switch which is tied into 30.. the other end of the switch is connected to 86

- of battery wento to the negative of the seat which is also tied into 85

and the GREEN/ orange of the seat is connected to 87

now when you say that i should connect it to an accessory.. i would use my ignition for example

i would connect my ignition to 85?? is that right

thanks for your help man i appreciate it

85 is ground. You should remove the constant wire from the switch. Then connect an ignition wire in place of the wire you just removed from the switch.

hmm alright, well which one is the constant wire?
86?

once thats removed and i replace it with my ignition wire.. where do i connect that to?

WOW....

30 goes to your constant power...(battery). the 14 ga wire from the battery!

85 goes to ground

86 to switch. other side of switch goes to ignition power in ignition column

87 to the seat. done! now to your passenger seat...

read the posts more carefully....it'll save you some time and headaches!

...half of the truth can be worse than a lie. <----Roger Russell said that..

A constant wire is a wire that always has 12 volts on it. A switched or accessory wire is one that only has power when the key is in the Acc or On position.

So to answer your question, yes the constant wire was the wire you had conected to 86.

well joch1314 if you read the posts you would see i already got the just of it, i just needed verification on the wiring & terminology .. which you gentlemen have done. And i thank you.. once i weld on my new brackets and get everything installed i will let you guys know the final result

Thanks again
