450 Lower Fuse Box Pin Out

Mod Details
PremiumNo Difficulty Mod ID1711 Creditevilution For450 Fortwo Linkhttps://www.evilution.co.uk/mod/450-lower-fuse-box-pin-out.htm Copy to Clipboard

The lower fuse box is ONLY found on the 450 fortwo with the 600cc petrol and 800cc engine built between 1998 and December 2002.

It’s located under the carpet, under the seat on the nearside of the car.

You don’t have to remove the seat but it does make things easier. You can push the seat forward and work between the gap in the carpet.

You’ll see a long thin black box with 3 connectors.

It has 3 connections.
