Default 1.6l injector harness question

I'm installing a vvt on my 1.6 chassis. Unfortunately I sold the 1.6 engone with the injector harness on it. I'm doing sequential injection but I need to know which color wire goes to which injector in the 1.6 harness. I'm using the vvt injector harness but I need to connect it to the 1.6 engine bay harness on which I will be adding 2 wires for the extra sequential injection.
Thanks

looks like yellow to 1 and 3 and yellow/black to 2 and 4, with white/red being common 12V supply

How do I do this when the engine is not running? This is an honest question, is there a way if the injector is not being fired?

Yes, you put one of the leads on the ecu harness pin Sean provided, then you go out to the engine bay with the other and poke wires till you read no ohms. Some have a beep mode, diode check, makes it even easier.

The wire colors Sean gave you are for the stub harness you gave away. Who knows if that's right for the car side harness, they both might be grey.

That makes sense, thanks for your help.

Actually those colors are what are at the miata side of the boomslang, which should be the same a what's on the engine side of the firewall.
