Wondering of I can use this OEM Starter relay for a rear aux light.

Here is from the FSM.

Any info is greatly appreciated. Aloha

My gut says YES, but I'd check the amperage draw just to be safe. I just don't see it drawing much no matter what, you should be fine to use it for anything.

:couch2:

Considering that relay is meant to feed a 40A circuit, it will handle lights no problem. Any reason for not using a standard Bosch-type relay?

 

[busmup808]

Just seeing of it can be used because it came with my Tacoma front clip conversion and I didn't have to go to the store and buy one.

I know how to wire the Bosch-type relays, but how do you wire these ones?

Meaning, where does the switch, the ground, positive main, & relay on the relay itself. There is #1, #2, #3, & #5.

1 - switch
2 - ground
3 - to the light or whatever else you want powered
5 - battery +

Thank you very much

Ok here's the deal. Current setup, I'm using a OEM fog light switch

The switch has 3 male positions
#1: GROUND
#2: POSITIVE
#3: RELAY

Now I just installed a stalk fog light switch

This switch only has 2 wires
#10: GROUND
#11: POWER

THIS IS FSM

Now the big question: HOW DO I WIRES THIS SWITCH UP!

Big ups to [MENTION=75868]Ed_C[/MENTION]

Here's a blown up picture

You don't need the positive because the stalk has no built-in pilot light. The ground wire goes to the DRL relay and the relay wire goes to the fog relay.

Should of say that my T4R is a 98 Limited. I have no DRL. The FSM is for a 02.

There isn't a ground on that switch. One leg is power in and the other is power out to the relay.

It's the same as any two pole (non-lighted) switch. The switch just completes the circuit on one leg, either positive or negative.

Wait, let's get this right. If you install the stalk, on a non-DRL rig, it will send ground out the Black/Red wire from pin 11 of the plug from the stalk. I'm looking at the '99 wire diagram for a USA (non-DRL) 4Runner. It is set up to switch GROUND. There is no doubt about it. I'd link it, but it's my paper copy.

So what you have to do is connect that Black-Red wire to the coil of the relay you are using. It will provide GROUND. Then you have to connect the OTHER side of the relay coil to the 12V+ power supply to the fogs. Then the stalk will trigger the relay as it is set up to switch GROUND and fogs will be available anytime there is power to the fog circuit. Or you can tap the 12V+ from the low beams, parking lights, any key-on circuit, or a full-time, depending on how you want the fogs to behave. The only other way to use the stalk with an add-on relay is to go get the White/Black (not green/black as in the 2002 set-up) wire to the stalk switch at Pin 10, take it off ground and connect it to a 12V+ source. Source depends on how you want the fogs to behave: lows only like stock, lights on, key-on, or anytime.

I strongly suspect the first way is easier.

Sorry, my first response in the previous post was for using the stalk with the factory relay.

 

[Ed_C]

I'm heading to work right now,will look into it after.

So you want to wire up some lights currently connected to that dash switch and control them with the stalk instead?

Correct

[MENTION=10169]TheDurk[/MENTION] could I get a picture of your FSM please on the fog light?

I was assuming that he was running his own wiring and only using that diagram to show the switch as used in the factory setup so we could see the two wires.

I didn't see it that he was using it in conjunction with the DRL or any other factory wiring.

He has to plug it into the factory harness or he will not have headlights or blinkers. That's where I was coming from.

The only factory wiring I am using is the pigtail from the switch itself. The rest of the wiring are coming from the relay. I am using my own wires to wire everything up.
