Almost all OEM injectors are High Impedance. I can't say for sure they are in the JK but I would assume they are.

You can test them using a multimeter if you have one.
Quote:
Low Impedance injectors are characterized as peak and hold types. They will have a winding resistance from 1.7 to 4.7 ohms.
Injectors with impedances from 10 to 16.5 ohms (high) do not require the external resistors.

Well, for me, that is the easy part. Just simply set your meter to measure "Ohms". Then place the leads on the two wires of the device. The real question is: "What is High and what is low?

Thanks Buddy and Here is the answer: If it is between and OHM is Low Impedance and if it is between 10 and 16 OHM is High...

You left out the numbers for the low impedance.

It's probably 1.7 to 4.7 ohms, like I posted above.

Low Impedance would be between 1.5 and 4.0 OHM
