So for my Exocet build, I have cut out about 75% or more of the stock body harness, leaving a large number of circuits for the interior fuse box with cut-off wires hanging out (I think I am using only 4 of the outputs from the interior fuse box for the car: the blue/red room wire that powers the ECU, the yellow cigar wire, which I am going to use to power a dual USB charging port, black/yellow Meter Power for powering the Dash2, and black/white engine controls). It was both late and dark last night when I was trying to figure it out, and I couldn't quite figure out how to free the pins. Google-fu is failing me, can someone describe what needs to be done to remove the excess wire stubs?

 

On my Westfield build, I left a couple of the wires for 'future use' and I've already needed 2 of them. One for my DRL's and a 2nd one for my heater fan.
If the pins won't come out, I'd just pull the wires out of the pins.
