Wiring RC 440cc saturated injectors obd1 into obd2 lude harness?? Please help
The pic above is cylinder ones injector wiring laying next to cylinder 2 injector wiring. Cylinder 1 is obd1 clip, cylinder 2 is obd2 clip. I've only soldered one so far because I want to assure myself I'm doing this right. Thing is all my obd2 wiring has a common yellow/black on each injector wires and a common color no stripe. OBD1 all have a common red/black and a common color no stripe. You'd think cylinder one yellow/black would go to red/black on the obd1 clip right?

This is looking directly at the clips, the obd2 clip on the left has a little positive mark on the left terminal, on the obd1 clip the positive is on the side of the connector on the left side. This is confusing but really there's no other way to explain it. If I've got both plugs facing me and the positive is on the left on both clips then this is right, or wrong?
The commonly-colored wire is always the positive side.
Other than that, I don't think the injectors require any particular polarity. But better safe than sorry, eh?
PS If possible you should try to keep your wire colors consistent if possible. It might save you a bit of trouble later on.

Thanks for helping me finally, rickv on sho told me since it's a dc circuit it shouldn't matter. So if I've got 4 yellow/black that are common it's def positive right? Which means I've got them hooked up wrong as of right now?

Looks like it.
The wires that are the same color for each of the injector clips are the positive leads.
The similarly-colored wires all junction into the 12VDC+ distribution block at the driver-side shock tower. They're all a part of the same circuit and should have continuity between each other.
The ECU grounds the negative side of the circuit to switch the injector on when it wants to fire an injector.
I'm not sure that it really matters that you have them backwards, but speakers are electromagnets too and they're affected by polarity.
