Hi guys just started to wire the two wires required for mfsw button connection .Thanks to your threads i thought it would be reasonable easy Wrong!!!!!!.Your threads say pin 9 to 12vplus and pin 10 on the clockspring connector to pin 17 on bcm problem is that i think the pin 9 is already occupied by a wire, brown with yellow tracer I think that pin 9&10 are fifth and forth respectivly from the left on the top row , Am i correct or am i getting the position compltely wrong .Many thanks for any help as van is stripped ready and dont want to put back topgether only to strip again when i find right connections.

PEW

yes your right brown/yellow has about 4-5 volts but it is pin 11 not 9. (tested this yesterday)

looking at the diagram this wire is used for the horn which goes to pin 8 black/white on the squib.

on the MFSW diagram a orange wire which was blue in my mfsw loom connects to pin 8 on the squib then goes back to pin 11 but there should be no wire in this connector when you have a MFSW fitted so would recommend you remove it.

Just waiting for my cruise control with trip to turn up then will be doing the same.

Wiring was for the T5 gp but looking through other posts it is the same pins.

that wire (brown/yellow) should only be on vans without MFSW if someone would like to comfirm this I think it will be right.

looking at the MFSW wire orange pin 5 from the MFSW buttons goes to pin 8 of the squib then pin 8 goes to pin 11 other side of squib there is no wire in this position on my diagram for this setup. hence i would remove to be safe.

Hi Mike thanks for the reply am totaly confused now thouight i had the numbers right but obviously not would love to see pictures you took .my email is
wyattsinspain@hotmail.com Asyou can guess i live in spain but am coming back to uk for 4 weeks in august to hopefully have the wheel coded as it is a bit difficult to explain to spanish mechanics what i need ,hopefully i will have sorted this wiring before i leave for uk,if not i will have to try and get it coded in uk and sort wiring on return to spain. many thanks. Paul.

There is no need to snip this wire. I didn't on mine and there are no adverse effects.

Moreover, if you are wiring it up now, and want to add the mfsw later, then you'd be snipping the horn wire, so you wouldn't have a horn until the mfsw is fitted and coded

The horn gets switched differently when you put the mfsw on it.

So if you fit the mfsw, and don't plan to code it up till later, then use the original steering wheel harness behind the airbag, not the mfsw harness, or you will lose the horn until you get it coded.

Hope this helps.
