Technical Ignition Feed

[BRAV-OH!!]

You may have read my other posts where i was installing an aftermarket headunit (Pioneer F900BT) and was in need of an ignition feed for the unit in order to have it work. Most aftermarket units work with an ignition feed rather than the Can-Bus method that the original headunit works on.

There is a can-Bus adapter available (Thanks to Trekster for finding it).................

But at £50 it's an expensive method.

The obvious place to tap into an ignition feed is back at the ignition barrel itself. But that involves removing of a number of interior panels etc and is a bit time consuming.

Anyway I got the multi-meter out and started looking for a wire that became live when the ignition was turned on in and around the area of the headunit.

I didn't need to look far. Right above the unit there is the hazard switch. This has a wire that goes live when the ignition is turned on and works perfectly. Makes the job a whole lot easier.

If you place your hand up between the two air vents, directly behind the hazard switch, you will feel the wires and plug. The plug just pulls out by pressing down on the retaining clip on top of the connector to release it.

you could have added that to the FAQ thread where it won't be burried.

Will do

I just thought I'd stick it here for all those people who have PM'd or replied to the threads asking for help/advice on what I had discovered or had done with my hadunit as they were having the same problems as myself regards getting an aftermarket headunit installed and working 100%.

arent your hazards supposed to work even with the ignition off - thought this was an MOT requirement
