Fuel Injector Plug Mapping (4 Viewers)

[andersonoverland]

Anyone have the order/number mapping for the injector plug order for the 91’ FJ80 with the 3FE? My mechanic changed out my injectors with new ones along with new wiring harness plugs and the truck is running crappy now. He thinks he may have the plugs in the wrong order. Does anyone know where or how to find that? I have the FSM, but does it show that?

Thank you guys!!

IIRC, the early rigs are not sequential, are batch fire, basically work as two 3 cylinder motors. So among the the two sets of 3, it's not important what connector goes to which injector, they all fire the same time and amount. IIRC, the connectors are different colors, one color goes to the first 3, the other the second set.

2 banks of 3 injectors. All 6 have a black/green +12 wire and bank 1 (cyl 1-3) has a white/light blue trigger wire and bank 2 (cyl 4-6) has a solid yellow trigger wire.

Why not let the shop figure it out? I mean, they're the ones that dicked it up, so...
