4hp22-EH wiring harness / cannon plug

Post by ///Moe »

Does anyone know where to source the internal wiring harness or electrical connector/cannon plug for the 4HP22-EH automatic?
From what I can see it's no longer available from the factory and it seems difficult to source. I have a 1985 model.

I'm having trouble with bad connection in the electrical connector on the transmission housing.
It's leaking oil around the pins inside the connector. Enough to soak the pins, but not enough to make it wet outside of the connector.

Transmission is working well and seems to have no mechanical issues, but it goes into limp mode sometimes, which leaves me with only third gear and reverse and the transmission light comes on. Cleaning the connector, or moving it make the transmission go out of limp mode and work as normal again.

I know some land rovers or range rovers use the same transmission (correct me if I'm wrong). Does anyone know if it's possible to source a wiring harness from one of those that would also fit the BMW's or is possible to modify so that it fits?

And no, I'm not going to do a manual conversion so there's no reason to suggest that..
I have several other cars with manual transmission, both fun cars and daily drivers. It's nice to have a car to just cruise around with also.

Have you tried to find the ZF part number? There are several websites that have ZF parts diagrams.Then try a ZF rebuilder in Germany...

I found a few ZF parts sites through google, but non of them listed the wiring harness on their webshop.

That transmission has been used by the following auto manufacturer's.

BMW, Jaguar, Maserati, Puegeot, Volvo, Porsche, and Landrover.

You may elect to contact the various ZF dealers/repair sites by phone/email as my experience has proven not all on line vendors list all the parts they may have or can get.

This company indicates they carry wiring harness, they're in Australia, I would think you could locate the part closer to Norway.
