Hey everyone,

I tried to install a 12V port at the rear and was tapping into the 7.5A ACC port at the front (driver side in the EU). Strangely my multimeter showed 12 V on both terminals. Just wanted to run my fuse tap orientation through you guys before It blows up.

Pull the ACC 7.5A fuse and 15A P/OUTLET fuse,

With the ignition off use a multimeter to check resistance between the two fuses left then right terminals .

The sides that are shorted together are the 12V input side that connect to the ACC Relay contacts, so put your fuse tap common leg in that side.
