Brief Description: Made New GPS Wire/Sealed Firewall PassThru's
I discovered that the GPS antenna wire was too short and did not allow any room for attaching the connection onto the 496. I made another coax cable about six inches longer and ran it thru the firewall. The XM Weather wire was pulled out and rerun outside of the holes in the antenna bracket riveted onto the firewall. I did this because the wire had been run thru two holes in the bracket. If the antenna needed to be moved for any reason, such as changing out the aircraft battery, the wire would not have any play in it. The XM wire was then run thru the firewall pass-through. The firewall pass-through was fully inserted and clamped in place. The four pass-through's were then covered with RTV high-temp sealant.
