Hello peeps, I bought the 13b tucked harness a few weeks ago and finally had some time to work on it, ran into problems of where the connectors for some of the plugs are, so I was wondering if anyone knows where the: O2, H20, OMP, Boost, Fan, IAC. I tried searching and I couldn’t find any, I know I shouldn’t marked the plugs :/. Any help is appreciated, thank you

 

Not sure what you are asking, but see if this link and this picture helps. https://www.rx7club.com/3rd-generati...iagram-804336/

 

ah yes, I probably worded it wrong, but that’s exactly what I was looking for, thank you!

 

Another question, i put the crank plug on the higher one, im not sure which one is ne or g, it’s just labeled crank and cam and this probably sounds dumb but for the full function fuel rail, the longer rail is the secondary and the smaller one is primary right? I plugged the secondary injectors to the longer rail with the front being towards the front (since it sounds like that’s how it should be), just wanted to know if I did it right? Sorry if these are stupid questions and thank you for any help

 

the white plug goes on the upper crank sensor which is NE

longer rail is secondary

short rail is primary

 

Gotcha, thank you! One more question haha I got a ground kit with it, and im confused as the grounding on the stock harness was connected to the harness itself but now the rywire harness only has one ground that’s connected to it for the ecu I believe, the ground kit has 2 ring terminals for the wires so I’m guessing that doesn’t connect to the harness itself and it’s separate, question is would that still work the same as if it is connected to the harness itself?

hope that makes sense, I wasn’t sure how to word it. I’ve looked at grounding procedures and I know where to ground it but I thought the ground wires would need to be integrated to the main harness like the stock harness?

thank you

 

The ground kit is very universal, don't use it. Make a 4awg ground from the uim to the firewall and a 0awg ground from the center iron to the frame on the spark plug side. Thats all you need. You can add more if you want wherever you please but those 2 are sufficient

 

Gotcha! Thanks bro, one last thing, so it doesn’t have to be connected to the harness? Like how the stock one is?

 

There are only 3 grounds on the stock engine harness. There aren't any ground-ground grounds on the stock engine harness. What are you talking about

 

This, how it’s attached on the harness itself, where as the one from rywire has one just for the computer and no other ones. And the ones I’m getting have ring terminals on both ends

sorry haha

 

thats not the engine harness. thats the charge harness. as far as i know, rywire does not sell or make a charge harness for the fd.

take your car to a shop

 

that wasn’t the engine harness yes I was just showing an example of the ground that I meant, how it’s attached to the harness it’s self instead of 2 ring terminals, the stock engine harness comes with those grounds no? Maybe I’m wrong but yes I’ll take it to a shop when I get the chance to, thank you
