Anyone know how the traction control switch is wired in the STR? I know in my vett it was a momentary switch that simply flashed two wires once for off and once for on. I haven't found the wiring diagram in my searching. I want to use the tc switch to master arm my NOS so I will know the tc is off before spraying. Just trying to figure out if i can just use the switch or if i have to have it flash a relay ?

 

Input FH103-38 dynamic stability control switch: Normally open / ground when activated. (Connector 103 Pin 38)

Info from the 2003 S-Type Electrical Guide Figure 05.1

If you just put a relay in parallel, I think you might feed a false signal to the DSC control module.
You might need a diode in the circuit.

I can build a circuit for it either way just wasn't sure if it just pulsed the signal as a momentary or was a straight on off. This system is going to have crap in it LOL.

 

qwikcat, when it all works out have to admit a very nice and convienient place to arm the NOS. Bob, good work finding the schematic.

 

Yea should work nice. I can make sure the TC is off and don't have switches all over, win win. A relay will master arm the juice and open the remote bottle opener. A tps safety, fuel pressure safety and rpm window switch will all have to be happy and then i just spray away with a manual button. I will also have the bottle opener relay wired where on loss of power (ground) a single throw relay will close the bottle, assuming my guy can work it out. That way i don't forget and leave it on, of course the TC will reset when the car is turned off like normal.

Right now it is just in there for dyno/street testing and data gathering.
