Best way to wire switches

[ChrisF]

What is the best way to wire the "man fan" switch so the fan comes on when I like, and illuminates the rocker switch when on as well.

Same question for the "converter" lockup switch.

Relays?

Where to connect these for the most efficient and safe setup?

TIA

No relays needed, both fan and torque convertor switch needs a ground. So need you get a illuminated on/off switch. There is switches available with led or a small lamp for illumination and the switches gomes with instructions to make it easy. E-mail me if you need more info.

I just did mine this weekend, For the fan i used a micro-switch, ground, and for power i just spliced into the fuse box, and then spliced into the green/yellow wire from the sensor on the manifold.

I don't believe anyone answered the question or maybe I missed it. Both the hi speed fan and the TC lockup are completed by using a switch to ground. The question was how to hook up a lighted switch to tell you the switch is on. How do you accomplish this when all the switch is doing is connecting to ground with no 12V for the lite on the switch ???

For the fan, I had to run seperate wires from the power to the fan to the light (this will also tell me when the ECM turns the fan on). I don't have a TC lockup switch, but if you run a wire from the (+) of the light to a +12V source (live when the key is on) and then had that tie into where the TCC solenoid wire comes into the switch that would work. Then when you turn the switch on, it would complete the path for both the light and the TCC. This way would also work for the fan, but I wanted to see when the computer was turning the fan on as well.

Ok, I got ya and understand with a separate light. But I guess I thought the original question had to do with a rocker switch that lites up. I don't think there is anyway to make this switch lite while completing a ground which is what you do when activating TC lockup or switching to hi speed fan.

I was typing a reply on how to do it, but then I started to think about how the lamp must be arranged in the switch. If there aren't seperate terminals for the light itself, then it doesn't matter really if the switch is in the ground line or not. It's hard to explain unless you know Kirchoff's voltage and current laws, but if there are no seperate terminals for just the lighted part, then I'm willing to bet that the light will work great if you hook it up like it didn't even have a light. That means the light must be in series with the circuit and just adds one more load to the circuit. So then the ground doesn't REALLY start until after the light. But as I said, it really depends on how the terminals are setup.

You use the +12 volts switched that lights the switch lamp to signal a relay that switches to ground for the TCC and fan switch controls.

A relay is needed with that type switch without separate bulb terminals, or else you simply go with a DPDT switch and turn on your own lamp mounted next to the switch.

I did it. I got three switches on my consol , one for the fan, TC lock-up and line lock. The switches I have got all different color LED on it to illuminate when its switched on.

Okay, I was going to ask this when the thread first started but felt it was a stupid question. I guess it's not so stupid.

All the illuminated switches I have have 3 blades:
12V+
Ground (for the lite)
ACC (the device that gets the 12V+)

The lite in the switch draws a teeny bit of current from the circuit to illuminate. If you're switching ground, though, you get no juice to the lite. But what if you did this:

Ground
12V+
ACC

The lite would get juice, and you're switching ground. Or are you? Would the ACC blade get 12V+ somehow and you'd bake whatever was supposed to get ground.

I thought of going the relay-route but got to thinking about how many relays I'd need. It made me tired, and I went to bed.

I may not have this right since I wired mine about 4 years ago but I am pretty sure when you ground the circuit you will have current in the ground leg. I have a Kirban 5 switch panel in the ashtray. I ran a common ground through all of the switches to a bolt on the firewall and then just took the fan ground and converter ground and ran them to the middle leg of the switch, switch lites and the switches perform their function. You have voltage available in the line, It needs to be grounded to complete the circuit. I know I have no relays, and there are only two wires going to each switch. The light in the switch is in series to ground.

My line lock is wired differently since it breaks the 12+ signal to my momentary switch on the shifter. A single ground is connected (this only grounds the light) and the 12+ goes into the 1st leg of the switch, when on the switch lights and then I have power to the momentary switch, hit the momentary and the additional LED light I added at the console gauge cluster goes on. This light is seperately grounded and fed directly from the 12+ to the line lock, if the light is lit the line lock is on. Lighted switch in the ashtray only indicated power to the line lock is available.

Clear as mud. If you follow the instructions on GNTTYPE you should be in pretty good shape.

I'll have to agree with Allan (Salvage) on this one. There's no way to hook up a 3 prong switch with a toggle lite (prongs are power, accessory,& ground) when activating an accessory by going to ground WITHOUT A RELAY if you are trying to LITE the toggle lite and also activate the accessory.

To have a lite, you must wire in a separate button light or use relays as Allan said.

 

[salvageV6]

Actually I am wrong on that one lol. Bulbs don't care a damm about polarity so use the switch for ground and hook the ground lead for the bulb up to +12 volts and it will work fine.

Ooops.

Bulbs are forgiving and AC/DC too.

Sorry about the misinformation.

I use both lighted rockers and LED's for indicators prefer the LED's usually.

Lots of relays too.

Now, I have to disagree. While using the 3 prong type switch w/ lite as described in my previous post, there is no way without a relay to cause the lite to go on when using the switch to complete a ground.

 

[bob86gn]

guys, I just checked mine. My previous post and salvage's post are correct. Wire the lighted switch inline and it will lite when the terminal is grounded. As Salvaage indicated, lights don't care about polarity they only want current.

Depending hows the relay wired up, relays have feedback on the coil terminals, so you will have to add a diode.

Well, I really don't care about the relay idea. Wasn't my idea. What I'm saying is that the bulb on a three prong switch won't lite when you are flipping the switch to complete a ground. Where's the 12 volts for the lite coming from?

Then, guys are saying it will with vague answers. Please give details.

Look at my 2nd post.....you put 12V+ to the blade that is usually ground on the 3-prong, illuminated switch.
