Has anyone chased this yellow wire with a light blue trace to where it comes from? I guess I'm asking if there is an easier place to do the splice. I picked up a floor switch from pacbrack (PN C11745) which is going in tomorrow. (Nice sturdy switch, made to be booted around.) It was just over $100 cdn with all the local taxes and shipping. I figure then I'll have to keep my foot on it to keep the TC locked (it is a press and hold switch). That will automaticly keep things in the safe position until I think to lock things up. Should help with the braking effect from the pacbrake itself and launches while towing, and way cheaper then the ATS copilot. Hope the part number helps. NADP brought it in to Edmonton for me. (Thanx NADP) Going with the jumper instead of the resistor, for now.

 

Im very interested in that unit, do you happen to know more about it?

I'll try to get pics. Like I said, nice heavy duty press and hold floor switch. I'm gonna use it like a "reverse clutch" on a manual. I use my right foot for throttle and brakes anyway, from running manuals for soo long. Just step on the floor switch to lock up the TC and get more power to the ground. Shouldn't be too hard to release for 2 seconds for a shift either. Here is the switch I bought.

A switch is a switch, what I (or you) use it for is my buisiness. Hope this covers what you ment.

PS Go to the ATS site and look at the Co-Pilot and Camander Wiring Diagrams to see the change from the Orange-Black Traced wire to the Yellow-Lite Blue Traced Wire. from the 47re to the 48re.

 

Sorry, I know some about auto electrical (enough to be dangerous), but how do you know which way the diode should be wired to make sure it is going the correct way. I am about half way through the mod.

 

BTW...for those with 03-04's that are watching....you don't need a resister.

 

cqestad, I understand what you are saying about not needing the resistor for the 03-04's, I was asking about the diode for the indicator light. Which way do you need to run the diode. Blcoonrod said to make sure to wire it in the right direction. Thanks! Sorry for any misunderstandings

 

You can test the diode with a ohm meter to see which way the signal will go through. It will only test through one way. Most of the time the diode will have this on it >l the signal will go through the way the arrow is pointing and nithing will come through the other side.

For the indicater light mod. It will need to be wired in so that when the computer gives the lock up wire a ground, it is not able to feed back up to the light. If you put the diode in wrong. The switch will not work. And the light will come on when your computer locks up the TC. Make sure you splice the wire coming off your switch for the light before the diode, or the light will not work.

You will have the switch. one wire with 33 ohm resister going to ground
On the other post 2 wires, one going to the indicater light the other going the tranny. You need the diode in the one going to the tranny.

Sorry for the long post. Hope I helped clear things up for you.

blcoonrod,
What kind of LED did you get? Do you run a resistor in series with it also, and if so, what size?

I think the foot activated floor switch is a great idea as well as a second series switch under the dash. I'm thinking an old school floor mounted high beam switch could work, it would keep your hands free to drive/shift/drink/eat/whatever, and can probably be had for cheap.

This whole manual switch thing could also help prevent theft too I think if you turn the switch to "TC LOCK" when you exit the truck.
Crook breaks into truck, busts ignition to start truck, shifts into "D", truck stalls. HA!HA!
If you add the LED, then you'll have a light that tells you it's on when YOU try to drive away.

BLcoonrod, I see MTwallet drew a diagram. This looks correct as I understand it. As far as the resistor, you or someone else replied previously that this was not needed for the 03-04 models (pre 04.5). Is this correct, or do I in fact need the resistor?


Thanks to everyone for all of their help, this is a very good thread and will benefit all of us with the automatics.

The drawing looks like it would work, but it is not how I have mine wired in.

The LED I have is a small one from radio shack. Just drill the hole and it snaps in. It was around $1 I think.

As far as the resister on the 03-04. I am not sure as I have a 04.5.




Ground____33ohm resister______ switch ___________>l (diode)_____

_tc lock up wire.

And for the LED run another wire off the switch like this

switch_____________LED____________12v supply

There is no need for resisters or diodes on that circuit. Although if you wanted you could put a diode in line like the other drawing posted.

Sorry for the horrible blueprints. I don't have a scanner to post some better ones.

 

Blcoonrod, thanks for the additional info. I thing you need either the resistor or the tie between the relay. I wired mine from the tranny to my toggle switch and the toggle switch 2nd pole to ground w/o using the resistor or the "relay jumper".

The results were when I started out and was going about 15-20 mph and turned the toggle on, the truck all but about died. So this tells me the resistor or the relay jumper is needed. My diagram is as follows:

Tranny<------------1st pole on toggle, 2nd pole ---------> ground

I think it has to be like we have discussed as follows:

Tranny<-----[resistor]-------1st pole on toggle, 2nd pole ---------> ground

 

Sorry, I meant to put the resistor in the ground wire, correct?

 

It really doesnt matter where the resister is. It can be anywhere between where you splice at the tranny and ground. I just put mine in line with the ground wire.

 

I did not need a resister...just a switch to ground. Make sure your shifter is down in first gear if your going to try that again at 15-20 mph....or WOT. If your at part throttle...the converter locks...rpms/power drop and your trannny will shift up to a higher gear and LUG...
