Help filling in the blanks - RX7 Wiring Diagram
Although there's a great photo of a wiring harness that's taken apart floating around the boards, I'm trying to create one using the RX7 tech manual's diagram...that way it's easily identifiable which goes where because it's placed actually on the engine.
But I'm having trouble filling in the blanks...there's a few connectors I'm missing and I'd like to double-check my work. Can any of you help? This is going to go along with the Assembly Reference Photos I'm working on here: RX-7 (FD3S) Reference Photos Project Thanks for the help! http://www.hawaiitalks.net/rx7/assem...connectors.jpg |
To the right of the purge control is the Knock sensor, it's a one-wire connector. The connector to the far right is for the OMP. Not too big of a deal because you can't connect either of them to anything else.
The connectors you have labeled Turbo Precontrol, Wastegate Control and OMP are something else. Those three "T" shaped connectors near the rear Secondary Injector go to the ACV. |

I put a few on there for you. People can chime in but i believe they are right
|
Send me a PM when you get to the dash and front harness. I know those better than I ever wanted to. Good luck, and thanks for doing this.
|
Sure thing...I'm going to go through a couple of the most common and see about making them a bit more friendly.
Thanks all for the help! If anyone else can help me re-identify the ones I screwed up, I'd appreciate it. Thanks! |
Twisted this is how it should be:
Power steering is actually Oil metering pump ACV is the turbo precontrol (left) and wastegate (right) solenoids Cali EGR is 93 Ca and 94 all EGR Also The one directly above the "cali EGR" is the Turbo control solenoid Above where you have thermo switch there is the fan swich (thermo switch) to the right and the Thermosensor to the left The IAC is really the ISC (idle speed control) |
Great...thanks...I'll redo it in a bit, and post it for further proofing. Thanks for the help!

I do not see the other end of the coolant level switch. The connector to dash - driver side.

I don't believe that's shown in this diagram...
|
If you want a complete harness description then it needs to be drawn in.

I'm sure it's on another diagram...I won't be adding anything to this one other than what's on it, because I plan on going through the majority of the harness diagrams and labeling all the connectors. The driver's side of the firewall is the one after this. Thanks for the input though!

This seemed like a too good idea to not be updated.
The IAC (intake air control valve) is part of the ISC so that label would be correct. Please double check what I did to the picture. Are we definite on the water temp sender? I would have thought oil pressure. To the very left, where there is a text "Sec. Injector", there also is a branch of the harness. Where does that branch go? https://www.rx7club.com/attachment.p...1&d=1335434689 |
Looks good to me, the harness which runs off the page which you are referring to goes over the transmission and plugs into the gear sensors/switches there.
The water temp sender is correct as well. The O2 and AWS connectors are switched though, if you notice on the O2 Connector there is a small slit opening on the bottom part of the connector which corresponds to the male end of the AWS if I remember correctly. This diagram is also missing a small connector which plugs into the emissions harness, near the power steering.. |

LOL x 2
LOL #1, I thought this was the engine harness, this is the emissions harness. Looking a bit closer in the wiring diagrams I now know there are lots of harnesses. LOL #2, ArchangelX had started another thread where this already was answered. https://www.rx7club.com/3rd-generation-specific-1993-2002-16/need-help-finishing-off-wiring-harness-diagram-853588/ And Sephek made the same comments in that thread just a few months ago. It also contained this useful link: https://www.rx7club.com/3rd-generation-specific-1993-2002-16/1993-front-harness-annotated-connector-pictures-892648/ Well, at least I've done a more neatly looking version. |

I'm hopefully finished. https://www.rx7club.com/attachment.p...1&d=1335516532 |
