Hello Members this is my first post, I’m hoping to find answers in the interiors page.

My 1989 420SEL I have replaced my AC evaporator and have put the cars dash & centre console back.

I found a black & red plug wire not connected to the shifter, I believe there is 3 wires that plug in to the shifter.

1) the globe wire
2) the 3rd gear selector
3) the 2nd gear selector which is the one that’s unplugged.

I have test drive the car to determine that the 3rd changes but not the 2nd gear, if someone has a photo or diagram or can advise me where to allocate this plug thanks.

Welcome to the forum james.

I don't think there are wires for the gears themselves. This is all done via the position of the shift rods under the car.

The wires I am aware of are:

1) The bulb for when the headlights are on. I think this one is at the front of the shifter.

2) The wire to the kick down switch for the little 'button' that the shift lever engages with for the 'B' position.

3) Economy switch if fitted but I don't think aussie 420s are so equipped.

The neutral safety switch is on the transmission itself, so I don't think that is related.

Thanks Bryce,

The wire is zipped tied short to the end so it won’t reach the SRS box. It’s possibly was installed for US or Euro shifter for overdrive I’m not familiar with.

The globe wire is at the front correct 👍,

Thanks for your reply that should do it for me.

Kind Regards

If you have a 2B shifter it operates kick down switch to hold it second gear when activated. Even with the plug off the the shifter the Automatic transmission should behave normally

The european models had a switch for 'S' and 'E'. I think it stands for sport and economy. My SEC has it. I just leave it on S, apparently it impacts when shifts happen but I can't really tell any difference.

I wonder if the wire is pre-installed? My electrical manual is for US models which don't have it either.

Good morning Helmet,

Sorry for the late response, my 126 wasn’t fitted for the 2B switch so this wire would have been left like that ffom all 126 1989 I think.

Thanks for your reply that explains a lot.

Kind Regards
