I never thought something so straightforward would get so off track
I tried AZ, ecstuning, google, ebay, and more
Everbody lists the 722.6 plug

Is the plug part # actually transferable or is the .9 plug just not listed?

I plugged in R230 and I get 2035400253 (which shows as a 13 pin listed as being used in 722.6 & no mention of fitting a .9 )

Any help here greatly appreciated
Thanks

Doesn't matter I found what I needed
Thanks though

The 722.9 electrical connector is totally different. The TCU is internal on the 722.9, so the only wiring needed is for voltage and CAN bus communication. I think it's either a 3 or 4 wire connection. Given the small number of wires, it enters the transmission near the top and need no pilot bushing like the large 13-pin connector for its external TCU.

Why do you want this part? Is it leaking?

No I just want to err on the cautious side.

I've never heard of this connector leaking on a 722.9. Having worked on the one in my CLK550, it's a very small, simple seal where the wiring harness goes through the housing and it's on the top of the transmission, above the fluid level. The problem with the 722.6 was that it used a very large connector that required a pilot bushing with two seals and it was below the fluid level.
