I just installed a new cab on my 4120 (VERY nice!). I'll post pics shortly. I'm running power to the cab straight from the battery through a relay activated by ignition on. I need a 40A relay circuit - I have the following to power up: a set of 55W front lights, pair of 55w rear lights, strobe beacon, dome light, defroster fan, front wiper and rear wiper. What size wire should I use???? I already have the 40A relay, switches, fuse holders and all of the components - just need the size of the wire to run from the battery. I think I should run #8, as #10 is only rated for 30Amps. BUT - it is really hard to find crimp connectors for #8 wire - the common ones only go down to #10 wire. Thoughts and ideas?
