Wiring solution for heated seat switch

ProfessorDave · 12-09-2010, 03:58 PM

I have a two part question:

1. Does anyone know/have a diagram for the electrical terminals for the heated seat switch? I'm trying to determine which is power to the switch, if there is a separate connection for the indicator light, power out, and ground.

B. How might I go about making connections to these terminals without the connector/coupling (or, can I get the coupling someplace?)?

(OK, that was three questions

)

I'm going to use the "low" side of the switch to power up the "solid on" function of my EVO-R LED foglight.

Thanks!

professordave- if the service manual does not say, i would use my volt meter to find a common ground, then use a 9V alkaline battery to see if one of the configurations would lite up the indicator in the switch.

since the LED takes very little power to light (i am assuming) you dont need to worry about a relay, etc. any on/off configuration would work for your LED.

Looking at the switch

Looking at the switch

1 2
3
4
5 6

It looks to me like 2 and 6 are the illumination circuit and if measured in situ that would explain the lower voltage

3 is +12V from relay feed for heated seats
1 goes positive in one position (1 and 3 being connected)
4 goes positive in the other position (3 and 4 being connected)
5 is ground use to illuminate the position 1 and 2 lights based on position of switch

and obviously in the central position 3 isn't connected to either 1 or 4

I think I get it (no thanks to Ken's lack of confidence in my middle aged brain

). Thanks Whee!

No problem. Check out the thread on the DVD Hack too...

Whee! That is very helpful. Have you found a connector to fit those pins?

wheee! · 12-09-2010, 07:55 PM

Yes, I located the crimp style connectors for attaching to the spade connectors on the heated seat switch. They are from Canadian Tire part # 20-6929-8
16-14 awg female disconnects in .110" size (almost 1/8")

I plan on building a harness myself that will turn off the VSS and turn on the BackUp camera via the seat heater switch. Needs a relay to disconnect the vss though as the circuit needs to be broken not made....
