identify pre89 injector resistor

[JASONA70]

I think this is a pre 89 injector resistor

I just need to know which one is the ground wire. I think it is the white one but i am not sure, if anyone could chime in and identify this. I am wiring this to my 1JZ 550 injectors.

another question: Does it matter which resistor wire I use to wire the ground for the injectors? I was thinking I could mix up the resistor wires because it is just a big chunk of resistors inside.

my pre-89 resistor had red, black, yellow and white i think (not sure on all of them tho)

I don't have the other end of the connector.

i dont think it actually matters as long as you wire injector pairs into 3 of the wires and 1 of the wires back into the line they all merge to

If anyone is interested I flowed/Cleaned my injectors. I know in the past people had some doubt about USDM 550's but it seems like mine came out just fine. I've read on a couple of threads that some 550's flowed close to 440's, and some flowed at 550.
