I'm trying to wire my Defi control unit to the car, by using the fuse box. Currently theres 2 connectors, which I think are for fog lights? The car doesn't have fog lights anymore, so I might just pull the connectors out.

My question is, where can I get suitable connectors for the fuse box? Can I reuse these? I need 3 connectors for my Defi.

Another question is, can I run more than 1 'accessory'? Like splice into the connector and have 1 connector, for example, feed power to 2 things? Is that alright to do? Sorry, I'm completely useless at wiring. Thanks in advance for any helpful info.

Of course, as long as you don't exceed 80% of the circuit's available load you'll be fine. A few gauges whouldn't pull much even with the lights on. Those pins have different functionality and different amp ratings, you need to check the helm manual to figure out which is which. They vary but there are always hot, accessory hot, hot with lights on, etc.
