Hello everyone, I need some assistance to push this project across the finish line. I cannot for the life of me figure out how to get this OEM rear heat switch wired up in a completely functional manner with working indicator lights. I have spent hours scouring the forums and trying different wiring configurations and I have managed to get this switch to function properly as a switch, but I cannot get it to work with the green and orange indicator LEDs functional.
I have a pair of Stedi type X pro lights wired up on my ARB bull bar. The relays are both purchased from Stedi. I had it working as intended with an aftermarket custom two button LED switch, however I was never able to get the lighting for this switch to function properly and the switch and lights dont match the other stock dash buttons.
I am looking to repurpose a 3 way genuine toyota switch to have a hi-off-lo function. It is originally a rear heat blower motor switch from a toyota avensis approximately 2003 era purchased off ebay.
My goal is to have the hi position tie into the relay I have that is piggybacked off one of the high beams. This will cut on and off with high beam switch.
In the low position I will have it operate a second relay that is tied directly into the battery power and functions regardless of what other lights are on (or even if the truck is on for that matter). in the middle position they will be off all the time .
I have been successful in wiring this rear heat switch to work and trigger both relays under the above described conditions. I have also been successful in getting this rear heat switch to illuminate and dim with dash lights. I just cannot get the green and orange LED indicators to work when the switch is activated in either the hi or low position.
there are 6 total pins coming from the switch. 2 are for the dash illumination and rheostat circuit and I jumped these from a nearby switch. Wires are green and green/white.
the remaining 4 pins I have as
-12V power in
-Hi mode relay 12V out
-Lo mode relay 12V out
-Ground
I have identified two different configurations in which the switch functions properly. depending on how I orient the 3 different 12V wires. and interestingly the switch still works without the ground connected to anything. It seems the ground is only required to light the indicator bulbs. I have since acquired two separate identical switches and one of them I desoldered and flipped the orange and green LED light contacts as I read in another thread that this was required but it wasn't successful in getting the LEDs to work. That being said, I have no way to confirm that my hack job de-solder re-solder job was effective or that the LEDs do indeed work at baseline.
My understanding is that the stock circuits on these dash buttons is negative switched, which somehow plays into the illumination of the indicator LEDs. I think that my current setup is positive switch just based on that being more likely since I am using new Stedi relays/harnesses.
I cannot find a wiring diagram for this switch so if anyone has that it would be hugely helpful.
Attached are photos of the switch and internals if these help anyone decipher further. It appears there are the two LEDs as well as an additional diode and a resistor but I can't quite figure out how to use this information to get it functional.
Thanks in advance, any help is appreciated.
