The column stalks in K2 Sherpas are shared with the Metro, Maestro and Montego, along with the instrument panel and clock. Some switches have thin white strands sticking out, these are the fibre optic leads for the illumination (not fitted to all models). This Metro switch had no main beam but the flash worked, which seems a common fault, so I decided to take a look.
The plastic slide in the centre of the photo fits into the body on the left, and slides up and down as you push the switch between flash, dip and main beam. As it slides, the contacts join up the appropriate circuit. The small piece of copper next to the slide is the contact, which has burned and fallen out. The contacts on which it slides are also burned and some of the plastic has melted (below). I might have a go at repairing it another day.
For testing purposes, this is what the pins do (as far as I can tell from looking at the switch, I will do a few checks on the van wiring to confirm):
| 1 | Power in |
| 2 | Headlamp main beam output (flash and continuous) |
| 3 | Headlamp dipped beam output |
| 4 | Headlamp circuit input |
| 5 | Hazards |
| 6 | RH indicator |
| 7 | Sidelight circuit output |
| 8 | Hazards |
| 9 | Headlamp circuit output |
| 10 | Horn output |
| 11 | From flasher relay? |
| 12 | LH indicator |
| Centre pin (brown) | Joined to pin 1 |

Another Metro/Maestro/Montego item, I wanted to fit an instrument panel with a rev counter. I have found there are two different sizes- 290mm (originally in the Sherpa), and 330mm. I've bought a 330mm item with rev counter and a round pin for the trip reset, rather than the more usual rectangular item. Written on the bottom is LM10, the development code for the Austin Maestro. The panel has two connectors, the first with three pins, then a gap, then another seven (I shall call this A) and the second (B) has six pins before the gap and four after the gap. As far as I can tell from looking, the pins are as follows:
| A1 | To engine temperature sensor |
| A2 | To fuel tank level sensor |
| A3 | Earthing this pin illuminates the bottom left warning lamp (not used on this dash, but on diesels is the glow plug lamp) |
| A4 | Brake pad wear warning lamp |
| A5 | Instrument illumination |
| A6 | Brake pad wear warning lamp |
| A7 | Choke warning lamp |
| A8 | Low brake fluid sensor |
| A9 | (see note below) |
| A10 | To parking brake switch |
| B1 | To oil pressure switch |
| B2 | Indicator RH |
| B3 | Sidelights |
| B4 | Indicator LH |
| B5 | Earth |
| B6 | Main beam |
| B7 | Trailer warning lamp (see note below) |
| B8 | Alternator |
| B9 | From ignition circuits |
| B10 | Rev counter signal in (from ECU or ignition coil) |
A9 is something to do with the brake warning lamps, it possibly overrides the parking brake and low brake fluid warning lamps for some reason. The trailer warning lamp was fitted to Austin-Rover cars and vans and although I'm not certain of its exact function, I believe it's plumbed into the flasher relay and allows you to check some of the trailer lights without getting out of the car.
From a quick look it appears that the two panels use the same connections, so apart from the physical size, are interchangable.
