Coding for rear wash?

[JamesWebb]

Is it necessary to adjust the coding to reverse the washer pump (to direct the fluid to the rear window)?

Thanks,
J

It’s not coding based, it’s done by wiring. A non rear wiper stalk has a plastic tab blocking out the contacts.

The pump for a rear wiper setup is also different with dual outlet, vs single outlet.

Hi there, and thanks for the reply.
Just for your info, I have removed the tabs (and now the stalk pushes forward, operating a contact) and I've replaced the pump with the dual outlet, the second one running all the way back to the rear wiper spray outlet.
I've also assumed that the sprung stalk forward push will operate the wiper and the washer at the same time. Do you know if that is correct?
Thx
