usually the rabit and hare thing are fast and slow speeds.
any ideas what the van was before it was converted? something that used a pto, tho i guess you dont have a big hole in the roof from a cherry picker being removed, but if it was a utility van, the pto would have run the generator and air compressors,
where is the red light?? in the dash or added later? what does it light up? what i'm thinking is in the hare position it should hold the engines revs, have you tried reving it a little then pressing the switch to hare to see if it's a throttle hold??
