jrsc vafc ecu wiring

ive had problems with the JRSC before i stored my car for the winter. main problems were the car was runing lean and wiring between all my electronics to the ecu. I stored the car for winter kinda pushing my troubles aside and its time i get in there and wire it up correctly so i can finally hit up the dyno and make it all come together.

So my main problem is how am i wiring the vafc between the ecu, jr black box, and j&s safeguard? what order should the wiring be in?


I also just saw this VAFC Harness Group Buy - Plug and Play! , would that help clean things up, right now my wiring is a mess!!

I know im bringing this post back from the dead, but does anyone have a diagram of all the wiring that goes between The ECU, JR EMS, VAFC, and J&S safeguard? What i mean is which unit alters the signal and then sends it to whom before its all recieved by the ECU itself.

I know i keep bringing this up but i rewired everything and im still getting a check engine (vtec solinoid). Is there any way i could get one diagram with all the wire, haha i know it requires some time or work but is there any way anyone can help me so i can make this all work and we could use it as a reference for others who would be runing a similar setup or the same electronics. Thanks again for all the help!

If you are getting the vtec code, you probably didn't wire the VTM wire correctly.

Yup no VTM is connected. I looked at the wiring and im looking at my VAFC instruction book and it doesnt say where to wire the vtm. Do you guys have a link or any help on where each wire is suppose to go on the ecu between connector A, C, D?

when i wired a buddies of mine up, we had to crimp all the wires together. If we put them in series it would throw like 3 codes. He had all the JR electronics and an apexi VAFC. Maybe this will help.

VTM wire is C15, blue/black. Cut it. Engine side of the wire goes to nothing. ECU side of the wire goes to the VAFC VTM wire.
