Left side gas pedal wiring problem...

Steve Mallett · Aug 10, 2018

Hi all. Hope someone can help me. I have mounted a left side throttle pedal in my Cee'd CRDI (Diesel 1.6 Auto 2010) for my disabled wife. The pedal is mounted but now comes the interesting part! I drive the car also and need to keep the right side pedal. Which connections on the throttle pedals need to be switched to enable one and disable the other. No relays, just a simple 2,3 or 4 pole changeover. Hopefully not all six!
Thanks in advance.

Hi,you will have to be careful how you achieve this...

For one,the ECU will see any change or delay,as a fault,and due to the important safety concern,of it controlling speed,it may flag a light or limp mode.

The second issue,is any modification you make,may require assessment and approval,from insurance,manufacturer or type approval accreditation body.

I know for a fact,that dual controls have to fit the above,and i will absolutely guarantee that any call you make to a dealer,will reveal the above.

you need a wiring diagram ideally which shows how the pedal is connected to the ecu. It could well be 6 wires, in which you will need a 6 way changeover switch....eek.
As mentioned ECUs are devils and are always looking for problems so you will need to operate the changeover before turning on the ignition.
If you have installed the pedal then it should show how many connections there are. It is likely you need them all.

2 way light switch fixed to the dash board lol, connect one pedal to one strap and the other to the other strap, job done

If i was doing it...and i'm not,and pleased i'm not...

I would have a secondary pedal,linked mechanically to the first,via bi-directional cabling or other means. Done in the proper manner,this is an "addition to equipment" and not a redesign and new install.

Hand throttles/accelerators are also accepted practice,and may be available. It is as well to check what accepted additions are allowed on any particular vehicle,as some items,such as towbars,are just not permitted.
