[quote author="@nickwheeler" source="/post/2722532/thread" timestamp="1646530101"][quote source="/post/2722531/thread" author="@foxmcintyre" timestamp="1646527839"]Is your mystery wire a gearbox sensor for the MX5? They have a reverse light switch for well, the reverse lights, and a neutral position switch which works in tandem with the clutch pedal switch to allow the ecu to see if the car is in ‘drive (in gear, clutch released)’ or ‘neutral (or clutch depressed)’. [/quote]The mystery wire
is for the reverse lights. But you've just cleared up why there are two other switches on the gearbox instead of just the speed sensor, and what the switch on the clutch pedal does. Which is a big help.
There are two 4-pin plugs near the passenger headlight that we still need to identify[/quote]
Anyone clever on here …..?
@rich this is the set Nick mentioned.
They are on the passenger side loom, toward the,front, but behind the headlight plugs.
And the wires feeding them.
Thank you for any help identifying them.
