Question: In my diagram I have two fuses. The reg/rec–battery and the starter–m-unit. Reg/rec wire is small enough to use a normal inline blade fuse holder but the m-unit wire is, what looks to be, 8awg-ish. All I can think of to use are those car audio plastic encased fuse holders which use glass fuses. Is that what I should be using?
And Cal, if you don't mind, can you post or direct me to a picture of your wired up m-unit? I just want to see how things are terminated, sheathed, screwed, etc.
