Couple questions, in the midst of finishing up the wiring. I bought a harness from rywire and the injector wires are labeled inj prim F, inj prim R, inj sec F, inj sec R, inj 5 and inj 6. They don’t have a 20b harness specifically but they modify the 13b to work. I’m assuming “F” and “R” mean front and rear, which basically leaves me with the question, where to I put 5 and 6? And other question is, what is this plug for in my adapter harness? I didn’t get a diagram for the adapter harness but I can seem to find anything where this one would plug into. Thanks for any help!

 

You're welcome to reach out to me for a wiring diagram PDF to make sure everything on here makes sense. Should be programmable to your needs with ease.

 

Rywire is pretty good about answering questions from their customers. No need to guess on anything, you can ask them and they will tell you.

To answer your question though, F and R are front and rear and 5 and 6 would be primary and secondary for the 3rd rotor. Presumably 5 being the primary and 6 being the secondary. No need to guess though, ask rywire directly and they will tell you which is which along with what that plug is for.

 

The answer is you're still going to have to rework the harness because you're doing something it was never intended for. Now is a good time to add in check engine light, all additional sensors, and contact your engine tuner.
