With the cowl finished, I moved back to a couple of wiring tasks. When I ordered the interior seats, I wanted seat heaters installed. I had the units shipped to me, where I removed the wiring harness and then shipped the heat pads to Abby at Flightline Interiors so she can build them into the seats. I had previously run a power and ground line from the VPX and forest of ground tabs behind the instrument panel to a location near the rear seat. Originally, I was thinking only one 12 volt wire would be needed for both front and rear seats, but decided each would need their own fuse. So, I programmed another terminal on the VPX for the second power wire—I’ll use the same ground wire for both front and rear seats. I followed the same path under the floor as was used for other wiring, then turned toward the right outboard side. I had run wiring for a 12 volt outlet on the right rear armrest—these wires ran thru a couple of rubber grommets, which were too small to get more wires thru. I clipped the terminals from the power outlet and pulled back the wires. Then I used a step drill to open up the previous holes to accept a small snap bushing. I mounted the heater relay on the side of a bulkhead, and step drilled a hole for the heat switch in the arm rest. Most of the wiring harness will be discarded (automotive grade wire). I’m waiting on some faston terminals to finish up the wiring on the rear seat. Tomorrow I’ll start on the front seat wiring.
