I am running EFI with the I squared system. My question is the constant 12V power supply to the Ford computer which bypasses the I squared system. Should this have a in-line fuse, if so what strength? Many more questions to come.

The stock Ford computer keep alive circuit has a built in fusible link in the pigtail ,so you don't need to fuse it.

Since you're using the I Squared system, and not the Ford harness, does that mean you removed the fusable link? I would think so, but I havn't used their wiring system.

I put my computer on a automatic reset circuit breaker. Doesn't need much, I think I used a 10A breaker. I prefer breakers over fuses.

Troy,

I'm using the same set up, and have no idea how to connect the i squared harness to the efi harness. I've tried fordfuelinjection.com, but all their diagrams seem to be for their harness, which isn't exactly like the donor harness. Could you pass on the info you're using to connect them? Thanks
