Cutting and resoldering Haldex wiring.

[Greig300]

Had the S3 on ramp today because the traction control light is permanently on... I knew why it's the Haldex plug has completely corroded and the pins have come off inside the plug connector. Can we cut the plug connector and resolder the wiring together? Without any issues? Thanks

Soldering them together will work fine... problem you will have is if you need to remove the rear diff for any reason you can't disconnect it easily and if your car is an early APY it may not have a fuse for the haldex so running on a dyno may present an issue if you ever choose to do so as you can't easily disconnect the haldex to run on 2WD dyno's

You could use bullets and sockets but unless you wrap the whole lot up properly to prevent water ingress then the issue may well happen again...

You could use RS232 serial plug assemblies

eg male & female

Thanks for the replys. I will probably just cut and resolder the cable and protect it all.

I've only ever seen haldex plugs with 7 out of 8 pins slots used

That looks really good I might buy that.
