I cant answer this but I got a question, why would you want this? Seeing Toyota has their issues with runaway throttles...I would trust a cable over a wire. good luck on what ever you choose, and be safe.
I would probably trust a cable over a wire also, but it is not a Toyota so I should be safe. If I do have a run away throttle, then I guess I'll get to see if I can still drive like I use to.
I agree, for that reason I’d rather have a cable.
About 10 years ago at my last job I needed to install a remote foot throttle on a GMC truck (one of the last 454s, and it was DBW EFI) and the PTO provisions in the ECM were not configured for a variable throttle. So we took a 2nd footpedal and wired relays in each of the TPS wires -- each relay switched between the corresponding wire on one pedal or the other. All the relays were triggered by the same circuit (with a few safety interlocks), and they switched over so quickly that the engine ECM didn’t know the difference.
I told you all of that so when I tell you all of this it’ll make more sense: I would bet that a person could install one (or several) normally-closed relays inline with 'something' on the engine and wire those relays to open via a 'kill' switch on the dash. Perhaps in the power wires to the throttle stepper motor (assuming there is a return spring somewhere), perhaps in the power to the injectors (some or all), maybe to the fuel pump (although that could cause a few seconds of lean AFs and possible engine damage, but if the throttle runs away for some reason I think that could be a smaller concern). If a crafty person put some thought to it I’d bet he could create a simple electrical circuit that would allow you to kick the engine into reduced power or a closed throttle.
Probably should go for the reduced power in case you get stuck on railroad tracks.
There is not chance that I am ever going to engineer any thing electrical like that. I have a guy for the electrical end of every thing. It is staying EFI for sure. [no carb] I was concidering using a 440, but even that was going to get upgraded to an EFI set up. Also, what motors are classified as a stepper motors? That term is new to me.
DRIVE EM, DONT HIDE EM.
