towbar kits - autumnboy
I want to fit a towbar to my C4 GP Citroen.

Do I need to have a specialised wiring kit or can I use the normal kit with a by-pass relay.

Read various things on Google, but it confusing.

You need to check if it is CANBUS if so then it will need to be programed into the ECU.
According to this link it seems that any type can be used but I would check with citroen or the suppliers first. www.solent-towbars.co.uk/model-detail.asp?pid=520
