Headlight relay upgrade

Post by jigarai »

I’ve built up a relay setup for the headlights as shown here. It also includes a headlight buzzer using relay 292.

I used a spare fuse box to build it on. When I install it in the van I will extract the main and dipped beam leads from pins A21 and B22 and put a double connector onto them that goes into the relays. The outputs from the relays then go to A21 and B22. It feels a lot more elegant than any other variation I’ve seen of this.

Open to critique here if anyone spots any flaws!

The buzzer takes a signal from pin A26 (license plate lights) and D7 (switched live on fuse 10 which is handbrake and seatbelt warning lights)

Fingers crossed it all works as planned. Aiming to get it installed next week sometime. Will report in here when I’ve done the next step.
