headlight washers
 

hi everyone

Looking for advice regarding headlight washers.

I have retro fitted them to my 75 but still can't get them to work.

Do I need anything else apart from the jets, pipes and pump?

Many Thanks

You need the BBUS to replace the horn in the plenum chamber and a T4 session to alter the ZCS coding so the car knows they are fitted.

DO NOT plug the bbus in until you have the zcs coding changed or things get very noisy!

You’ll need battery back up sounder for alarm (fits in near side scuttle) and then a trip to see a T4 machine to get it set up. I’ve had all this done a few years ago mind, and the last 2 years it has stopped working so just a quick fix behind bumper to get it through MOT ;)

Go on, what is a BBUS?

Battery Back up Sounder (A posh horn with a built in battery)

ok I have to ask it. What does a horn with a battery have to do with headlight washers?

Its part of the circuit, without it they don't function.

Is it a direct replacement or is there mods to be done

Plug and play ;) The wire for the BBUS will be hanging next to the alarm horn in the plenum.

Wonderful. thanks very much
