I ran another GMA 24 harness of wires from the GMA box across the forward main "branch" and then down an alternate path to the forward cockpit and out the firewall. This wire harness is for all the various engine and electrical sensors, and I didn't have room to run it thru the gear tower, so once I secure the bundle, it should be good. I started by laying the wire bundle out straight. I zip-tied the bundle about every 10" and then laced between the zip ties. I removed the zip ties, fed the wire bundle along the branch and out thru the firewall, then put another wrap around the bundle to protect it. The last thing - tidy up the wire bundle.
