hey guys, so my 91 na s5 was carb swapped by the previous owner and im almost done reverting to EFI, but im having trouble figuring out where all the connectors go
ive found a few of them like the injectors, maf, map, rats nest, and wiper motor but i have a lot more to go and im a bit over my head.
ive seen this pic floating around for awhile and was wondering if anything similar for my car is out there

 

Go to
1989-1991 (S5) RX-7 Factory Service Manual : 13B Etc - Mazda RX-7 Parts And More
And download the "04A fuel and emissions control systems" as well as the 1991 wiring diagram all the way at the bottom. Those will detail exactly what each plug looks like, wire colors, and so much more.
