Hi I need help. I have a 1989 transit ambulance. Originally it was a 3 litre v6 what gearbox would this have had. It now has a 2.5 di the early one with a four speed box with overdrive. My problem is I need the plugs that plug into the over drive switches. As I have none or the wires on the van too the switches. As it is revving like mad in forth at 40 mph I think it needs sorting. Dose the overdrive box belong to the diesel engine??
Please help dave.
