They are a Cu%T to get out, I just had mine changed after having no reverse lights for a couple of months. I cant recall which one is the reverse and which one is the neutral position switch but I think they are fairly close to each other. If you lights are still working you can test it bu unplugging one of the switches and chucking it into reverse and see if the lights work or start the car and chuck on the glow plug warmer/high idle switch and see if it brings the revs up, I believe it wont if you have the NPS unplugged.
