I'm not a dealer, but I'm at quite a few hours into a install on an experimental GX3 touch system, but allot of that time was studying, pulling out the pertainate(sp?) info making wiring labels/coherent descriptions spreadsheet & printing out, to build the harness....
so the next time(s) should be easier/faster I assume(almost 1000 pages of manual to sift through..)
this is second one I've been involved in(first was stewarts, (but the avionics shop built the basic bare harness for that one($6000++), I just finished hooking the other ends up to the sensors etc(except they were poorly labeled and i still had to go research the wiring diagrams on ever step)... this one is ALL the steps/harness)
I wonder what it takes to become a dealer? if that's whats required to install them(STC'd)???
the dealer up here is many months out/backlogged... it is only reason I got talked into doing it...
