yeah...so I hope I'm not the only one who has done this.

I was reading through the SR wiring Walkthroughs and thought I had it down. so I go look at my engine bay and find a plug, thats plugged into next to the fuse box and it looks like it's the one I need to do the swap. So, I cut it, and like 2 other plugs that were next to it, cause the website said, it's a couple of plugs behind the battery. when I finally got to the CA harness, only 2 wires matched the right color...hmm??? I go back into the engine bay and find 2 plugs to the left of the battery location that match exactly. so I cut those and wired them in.

the ones I orignially cut

the spot the came from

and where the correct ones came from

now my question is, has anyone else cut the 3 plugs off that mount right underneath the factory fure box? I haven't pulled the motor yet, so I don't know where they go to, I'm just wondering if I need to put them back, or if it's for something that I won't need wired up.thanks for advice in advance

IIRC I have one of those plugs to the right of the battery tray still unplugged. I have no idea whats its for and its not mentioned anywhere in the swap so I take it its not needed. I know the AC fan plug is near there.

The lower CA harness is no good.

I would prefer the KA harness over the CA.

If you are a jedi master, you could also splice in some vital accesories from that ca harness, but rarely does anyone.

I've got a CA lower harness on my car and everything plugged right into my SOHC KA chassis harness.
