Continued work finding best source for parts.
Explored options for solder sleeves instead of the Garmin suggested sleeve with braid.
Researched and selected crimp on ferrules for use with connections to the P-mags and CO detector.
Ordered all the wire I calculated I will need so I won't need to order any more. Until I run out of something... Ordered from Stein Air, Aircraft Spruce and Wiremasters.
I had been planning on installing one or two defog/avionics bay exhaust fans. After talking to Van's support I decided I can do without a fan and add it later if needed.
Ordered more splices and a few of the Garmin recommended solder sleeves and some other random parts I'd been saving to combine into one order. Once I try the Garmin recommended solder sleeves I will make a final decision on what to buy and place one more order.
