Got started on fitting the rack today. Doubler panel. The latest offering (Jan 2022) from MWPB splits the harness into two. One for the airframe and one for the equipment rack behind the dash. It is quite overwhelming figuring out where the tentacles of these wiring harnesses go at first. Unlike the rest of the Sling kits where you have many diagrams and the parts down to every last rivet and grommet. The MWPB panel and harness no install instructions or layout diagrams other than Facebook videos. You are also on your own sourcing any extra clams and tie wraps. Two things were needed to get started. Where do the ground and power busses mount, and which wires need to go through the firewall (so that I can get that done and fix the top skin). Once I got my bearings, it become s easier. The rack behind the dash has a sub-rack that is designed to mount an audio panel transponder and second com radio. It’s white heavy (820 g) and made from 2mm aluminium. I also was concerned about accessibility to service the audio [panel after the windscreen is fitted. I could not see how it could be removed. (Whereas the transponder can be removed with screws from below). I decided to remove the sub-rack to save weight and improve serviceability.
