Right - which is the "negative" (PCM) side of the IAC circuit. (white w/ blue tracer)

Hey, GF?, I've been looking at the wiring diagram tonight. The PCM controls the ground for the IAC (as well as other controls). The 12v source is shared with the boost controller. This 12v source is supplied through the fuse from the Main Power Relay. I don't see how a 1A fuse on the 12v source is going to to protect the PCM, as they are not connected. A high amperage situation on the negative side of the IAC could result in damage to the PCM.
Would you further explain your logic. I appreciate it!
Terry

Just some of jist --- The red / blue wire is the IAC connection / feed to the IAC by pass valve. That also is spliced up to the area of 4 fuses 20 to 25 amp.
The IAC -- white / blue wire goes to the PCM connector B. -- That's the middle connector on the PCM

Had a PM asking, so I wanted to just post a followup, this is what I made for mine. I should have made the harness shorter, but it was a little easier to assemble at this length.

It took me a while to find them too. ...quite a while, in fact. I work in the auto industry, so I had to reach out to some of my resources for some part numbers.
The connector bodies are ....
AMP SSC-2 Black Female
AMP SSC-2 Black Male
Usually, you have to buy like 5 million of them to get the 4 I needed. But I found a website....
www.CycleTerminal.com
...that sells smaller quantities, and even has kits with the terminals, locks, and seals. I already had the proper crimper for the metri-pack / superseal type terminals.
About $20 or so in the two that I made. The 1 amp fuses are also hard to locate, locally. So Amazon was the source.
