E4OD Converter lockup ?s
I want to add a switch to my pickup to control the converter lockup, I will be using a on-off-on switch, so it would be stock-unlocked-locked on the switch, but I also want to put a indicator lamp on so it lights up whenever the converter is locked, when the computer does it, or I do. So would this setup work? (Sorry for a kindergarden grade pic)

I don't believe the last one will because there will be a voltage drop through the light and it may not support the current draw required to keep the converter locked.
You could use a double pole switch and wire the indicator lamp or LED from another source. It would still illuminate when power is sent to the lockup coil, but the light would be isolated from that circuit.

so how would this work? Say if your off roading or racing you can turn the switch so your converter doesn't lock up?Because I have noticed my truck doing this recentely like when i am kind of getting after it and all of a sudden the rpm's drop and the truck kind of surges,I just figured it was the converter locking up.I know someone makes a box for the converter to so you can unlock the converter,but it was like 500 dollars and I didn't want to pay that much.So I'm interested in this let me know how it turns out for ya.

Bassicaly u can lock and unlock the convertor at will, or leave it for the computer to decide. When runnin down the hwy u can leave it locked, or when decending a hill for better engine braking. The more the covertor is locked the less heat in the trans. But have to remember to unlock it when stopping , or the motor will die. And yes, u could leave it so it doesn't lock when wheeling, or u could get it to lock in say first gear low range when going down steep grades, so you wouldn't have to ride the brakes as much.

So is a locking converter essentially another gear for a transmission? Say for instance I have an e40d and i'm doing 70 and it's in overdrive and then the rpm's drop off a little is that the converter locking up?

Quite a few of the GEN 1 Lightning owners installed a switch to disable the lock-up to race because the ECU will command the converter to lock, and stay locked @ WOT, after the 1-2 shift.
There is a good bit of torque induced through the transmission, and in the driveline, when the converter forced to stay locked and being in first gear will multiply this. Having the converter unlocked will offer a bit of cushoin. If overheating is an issue, you might want to consider a larger transcooler, deeper pan and even use a synthetic fluid.

Ya, when the rpms drop a bit at 70 mph that's the convertor lockin up, but try this, hold the speed steady, and tap the break peddle, the tach will jump up a bit than back down, that's the convertor unlockin and lockin back up, when its locked you will get better mpg than if it was unlocked.

Sorry if I'm hijacking the thread but i've always felt my converter locks up way to quickly and was looking for a cheap way to control when I can lock and unlock it.And no overheating is not a problem with me as I have a f350 with a pretty large tranny cooler already.I just wanted it for the same reason as many of the GEN 1 lightning owners did.

I'm worried about heat when I'm towing. And I want to keep the convertor unlocked, when I'm playin in the snow and stuff like that I'm sure 90% of the time the switch will be in the "stock" position.

Is this the right bunch of wires? Its the spread out bunch close to the middle of the picture.
Another pic, that is a purple and yellow wire, so I think its the right one, just wanted to make sure before I cut it....
EDIT: yep that was the right bunch of wires, and the right wire to cut.. I installed a # position switch, and it works great. didnt hook up a light though...
