I bought a lift to assist in the build. Before the 428 was installed, I wired the dash without removing it. A little tight, but I'm a big guy with big hands (and big gloves!). The heater went in but had to remove the bottom screws and tilt the dash out a pinch. But not all that hard. Even the wiper setup went in without too much trouble. My only complaint is that the heater goes on when I use the left signal and the lights go on when I turn the wipers on : )
(jes kiddin, it all works fine thanks to the simplified wiring harness from ERA)
