I converted to hei on my 69 a little while back and havent changed the reistance wire yet.I was thinking of running a #12 wire with an in line fuse fron the fuse block to the dist. What size fuse should it be? There is an unfused terminal marked bat in the center of the fuse block,It has power only when the key is turned,can I use this? I read previous posts on this subject. I'd rather not cut the harnes or mount a relay.I also read that some people couldn't shut off the engine after changing this wire, what's that about? If anyone sees anything wrong with my plan please let me know. Thanks.
