Project My 1987 VT250F2H Race bike

Hello all, once again I’ve stumbled back to this group after a long absence.
I’m still developing my VTR250 race bike and this winter really committed some major brain power to it! I’ve rebuilt and modified the stock engine I’ve been running for a few years AND am converting it to EFI!
I bought a 2010 throttle body set from OZ and build a NO2C Speeduino standalone ECU to run everything, got some VW Polo 1.4 turbo smart coils, GM IAT and water temperature sensors and a fuel pump assembly from an Indian Scout. Modified the fuel tank, made some adapters to mount aftermarket generic velocity stacks, made my own shortened throttle cable, made my own foam air filter and squeezed a wideband O2 sensor in my exhaust.

I’m hoping someone can help me with a little snag:


I am for an image of the wiring diagram for a 2009+ fuel injected VTR250. I have searched online to no avail.

I am currently trying to sort out the wiring of the Intake Air Control Valve, A1/A2/B1/B2. Four wires come out of the IACV but I’m not 100% sure of the plug pin location/orientation. I know one coil is the middle two pins and the outer two are the second coil…

I found this image of another wiring diagram that I suspect is the same but I can’t know what the plug orientation is. In the other picture on my bike you can see where I had to add an extended socket to my IACV because there’s no room to plug into it, it’s right against the bottom of my modified fuel tank.

If at all possible I would love to get a picture of someone’s four wires going into the IACV and a picture of the wiring diagram showing the IACV. Thanks!

oh BTW, I’m the 2023 Lightweight 250 Champion of Atlantic Canada!

 

I grafted in the top of a ZZR (GPX)250 fuel tank so I could get a keyless gas cap, also lowered the overall height
