May 20, 20232 yr I tried the search function but it just rotated and rotated.... Having now spent some time playing with my intended donor 99 EJ202 Forester, I find that the ignition coil gets it's power from the ignition switch - not from a relay. Surely nobody trusts an EJ ECU in use conversion to run faithfully on old EA ignition switch power for things such as ECU and coil ? ? From my most recent learnings, I would only be using the brown double switching 2M "main relays" as Fuji call them, or "ignition relays" as the rest of the world call them - for the reliability of two sets of relay contacts for the one demand. What have others done here? Given the number of EJ conversions, converters and people sayin "put an EJ in it " - I am expecting loads of comment.
May 20, 20232 yr Use the ignition wire that powers up the relays and ecu off the EA ignition wire via a fuse. Never missed a beat for me in my conversion and I was driving that daily for the best part of ten years until recently. Numbchux’s write up gives detail on this I believe. Cheers Bennie
May 23, 20232 yr I ran all mine right off the ignition switch just like factory EJ. IIRC the EA coil was powered the same way. Edited May 23, 20232 yr by Numbchux
