hey guys got a good deal on 4 injectors so i bought them. I was told they are ford mustang injectors but was tested and they are equal to 550cc.

The question i am asking how do i know if they are low impedence or high inpedence??

If i try them on car will the car work if they are low impedance and will the car turn on ???

They look just like the one that hrc has on their site color and everything i just need to know how can i determine if are high or low impedance

thanks

You can put a multimeter on both metal pins on the injector, and test the continuity. If it's up around 12-16 ohms, you're good to go. If it's in the 2-6 range, you've got the low impedance variety.

hey jason thanks i got the tester now what where do i put it in what frequency or what

thanks for help

You have to switch the multimeter to "Continuity" check and hook the positive and negative terminals of the multimeter on each metal prong inside the injector plug.

Hook it up and look for the reading.
