Thanks that will help me. If you don’t mind tracing the wiring and photographing the numbers on the vdo loom as they patch to the td5 loom. Have you used relays to bypass or simple plugs and sockets?

I have just obtained a couple of the pedal interface boxes with a view to put one on my td5 for throttle idle increase when using hydraulics. I do not have the wiring diagram or the manual. You mention you have the manual? Does it have the wiring diagram contained? If so could you let me...
