There's no such thing. Making all the lines thick enough to see the distinct colours would turn the diagrams into a cluttered mess, which is why nobody does it. The colour codes are clearly shown on the diagrams and require the most basic of memory skills to use.

this guy in the first gen section put a s5 n/a into a fb or sa
iam putting a s5 n/a into a 74 repu
i showed him the link to (http://www.cochran-racing.com/FSM/s5...systems_na.pdf) for the wirring diagram


and he said this "That link has all the info on how the engine controls work and all, but it doesn't have the wiring colors, there is a wiring diagram out there somewhere, can't remeber the link, but if i come across it i'll pm you"

my passenger side harness is missing the fuse block and batt termails so iam a little confused, also i wanted to 'clean up the harness and remove any unwanted things'
this is almost complete "https://www.rx7club.com/showthread.php?t=719859" ive done all the grunt work now for the part iam not so good at

True. The series four does show the wiring but the series five does not. BUT, someone did scan the series five WIRING and it WAS hosted by someone. At that time I downloaded it to the hard drive because what someone hosts one day may be gone the next.

It MIGHT still be out there somewhere. It was in the archives and might still be there. Take a look.

Ok. First is the Narrow band output wire. Other wires to follow someday, sometime in another gallaxy.

Well that's a piecemeal effort I made. I think the series five is still out there somewhere in a PhotoBucket form. If I run across it I'll give you a answer as to where.

IF you need something more specific than the above write back. By the way, Mazdatrix used to sell just the wiring schematics.
