P-mag wiring with Vans DC Load center and the ACS key-switch
 

Hi.

I'm installing dual P-mags on my Superior IO-360.
I'm also installing Vans DC load center EXP-2V and the ACS A-510-2 ignition switch (key-switch)

The P-mag wiring diagram says to connect pin 5 (+13,8 v dc) to the main bus via a switch and breaker.
I've installed two separate switches/breakers for this purpose, but here's the question:

Since I don't have a separate main bus, where schould I connect the wire from pin 5?
(I assume wire 5 is the primary power source for the P-mags?)

So far, my thoughts are to connect pin 5 to a pin on the EXP-2 panel which is always powered, for example the "clearance delivery pin".

Or maybe I schould wire pin 5 to the shunt or the battery? That way, the P-mags will be completely independent of the EXP-2 panel. And they are protected via the separate switches/breakers.

Second question:
Is it correct that the wires from the key switch to the magnetoes are the two shown on the P-mag diagram? (P-lead = "kill switch)

Or am I completely confused here??

In short: how schould I wire up the P-mags with Vans EXP-2 panel and the ACS igntion key switch?

I don't have P-Mags but ....
 

I used the DC Load Center (Exp-Bus) and a key switch along with a Jeff Rose Electronic Ignition.

I do not have the drawings before me now and the work was done over seven years ago but I wired power to the Electronic Ignition via a SEPARATE/DEDICATED switch (fused). That toggle switch is just to the left of the Key Switch which I think that I wired per the instructions.

The main point here is that I chose to have ignition be INDEPENDENT of everything else electrical. That way if the Load Center went up in smoke, I still had electrons going to the engine for firing a set of plugs.

By the way, our RV6 tip-up DID leak and I DID get water into the Load Center once. I think I had to shut it off and fly home on the wing of a friend.

always hot
 

Although I am not using the DC Load center, I wired my ignitions to the battery bus, so they're always hot when the breakers are switched on. I think the logic that you don't want to depend on a DC Load center or anything else keeps a critical circuit dead simple.
