Electrics Firewall Passthroughs

[rockitdoc]

I think I have finally got all my wires through the firewall. It has taken three pass through bungs. Two are 1" and one is a 1/2".

My question is whether I have stuff sufficiently separated to avoid noise issues.

On the port side I have the 1/2" hole with:
1. CHT 1&3
2. EGT 1&3
3. Man Presssure
4. Baggage Light Pwr
5. Stall Warning Horn Pwr

On the starboard side two 1" holes with:
Hole #1
CHT 2&4
EGT 2&4
Alt 1-Out Lamp
Alt 1-Field
Alt 2-Field
Oil Temp
Oil Press
Fuel Press
Hall Effect Current
Master Switch
Start Switch

Hole#2
Main Bus Pwr
P Leads for P Mags 1&2
Pwr to P Mags

Just a thought, but you might want to consider running the wires to each Pmag through separate holes rather than the same one. That way is there is a problem in one of the pass thrus (a short that takes out the wires in that pass thru?), you might not lose both Pmags. Same thing perhaps for the alternator field leads.
