Swapping A Series 5 Afm Into A Series 4 Rx-7!
I followed the instructions the best i could, but my car wouldnt start. Frustrated, I whipped out the trusty manual and compared wiring diagrams between the two series(s4/s5) and made my own wiring decisions, pulled codes and made more wiring changes.
so here it is kids, the definitive wiring instructions!
...........S4................................S5... ..........
GRN/ORG...............+.........GRN/ORG
............BRN/BLK+BRN/BLK.......................
............BRN/BLK+BRN/BLK.......................(join these four wires together)
GRN/BLU................+........GRAY(green wire inside gray insulator)
BRN/WHT...............+........BRN/WHT
BLK+BRN

note: my car has a 87 wiring harness-- according to the book the wiring is different between 87 and 88.

you can also use a v6 626/mx-6/probe one too. also k2rd can get the s5 afm connectors
mike
Second GEN? or the first Gen mx6, probe ect.?
hmm... did the mod from s4 to s5... doesnt want to idle right. it will die if i let off gas and when i start to go it sounds like it only runs on one rotor... but after like 2 minutes with my foot on the gas it will idle decently
