Really having fun now....
The basic install document for Skyview is Section 42C, 13 pages, came with the avionics kit.
Fired off a question today to a 12 builder already flying, what's with attaching Engine Monitor Module to firewall and no holes in firewall or dimensions of where it should be?
He replied, Oh you must refer to Section 42D, Skyview Installation Update.
I got a copy of it from Vans this evening.
The update to the original 13 pages of instructions is 35 pages!!
Yes, this is a learning process.
