Electronic ignition using Ford EDIS and Megajolt
Posted: Fri Apr 07, 2023 7:04 pm
I am struggling a little with the wiring of the EDIS, which has 12 pins, two of which (2&4) are not used. Curiosity got the better of me, and I checked with a multimeter if these pins connect within the EDIS to any other pins. 2 connects to 11, which is the alternative tachometer supply. 4 connects to 7&9 both of which are earth (ground).
I asked the supplier “Trigger Wheels” if I could use 2 for an alternative tachometer supply, and 4 for another earth connection. The answer was “use the connections specified in the instructions” I was expecting a more comprehensive reasoned reply.
My electrical knowledge is very basic (I can wire a two way lighting circuit) and does not cover electronics at all. Does anyone who understands an EDIS know if I could use pins 2&4? My reason for asking is that this would untangle my wires a little.
