Thanks because that header is labelled C0288 on my RAVE (2003 version).
It appears that our diagrams have major differences which is odd. Simon

It's the same joint though, although labelled differently is somewhat confusing I agree. I'm off to walk the dog, I'll leave it with you and Dougie Brian |

I'm looking at RCL 0544 ENG.

Pin 1 as you'll see brings +12v to the second pole (pin 3) which is then sent via pin 3 to the EAT and cruise relay when the brake pedal is pressed. That is functioning correctly. Regarding C0285, it's shown on pages 34 & 36 of Rave, and also on the Header Joints page 109. If you check out the C0285 Connector Detail in the library, it confirms pins 1-4 as being grouped and GR in colour. However my car does not have a C0285 header as it doesn't have interlock*, cruise or parking sensors. *incorrect, it does but without requiring brake input The fact that half of the switch completes an earth and the other half completes a +12v connection, must mean that it is in fact a double pole switch. Yes? Dougie.

Yes, true. I went out & checked pin 9 on C0286 which is the GP wire from the switch pin 4 (C0075-4). My reasoning for connecting to that header was that the switch pin 4 wire was/is inaccessible without some more surgery, and I made the assumption that it connects directly from C0775-4 to C0286-9 (9-11 are common). Pin 9 (and 10 and 11) on that header however tests as permanently earthed which will be one good reason why cruise thinks the brake pedal is pressed. The brake lamps work correctly so it's clear that my assumption was wrong, despite the diagram saying it was right.

Thanks guys for your input this afternoon - it's much appreciated. I'm in a much clearer place despite not yet having cracked the job, as a result. It's clear that I'm going to have to change the switch which I'm collecting from Rimmers in the morning, although I still don't understand why the connections from (allegedly) pin 4 test as permanently earthed despite the brake lamps working correctly. Perhaps my version of Rave isn't correct relative to my car. Or more likely I'm missing something. Either way, here's to tomorrow.
Dougie.

They're triggered, via the LSM, from the same C0286 header which you say is permanently earthed. How can that be? Simon
