The reason is to install you cut the O2 signal wire and patch the simulator in. When the Sim is off the O2 signal is sent to the DMEsince the simulator is in pass-though and the O2 signal is sent like the wire was never cut.. When the DME calls for Air Pump the sim goes active and cut the O2 reading and sends a 200mv signal to trick the DME into thinking the air pump is in and working correctly. Hope this clears it up a little |
Wow I'm an idiot lol. I've read and re-read this entire thread and it didn't click until you posted that. Thank you! I will test it when I get out of work and report back with my results.

Alright well looking at radioshak they only have a 1.0uf for the input to ground and they have a .1uf for the output to ground. Would these be sufficient given there voltage is a little high or is that just the maximum voltage they can handle?
