i know this has probably been asked but i was looking at Frequently asked question and its not in there or i cant find it but how do u know if the injectors are Low imp or High imp i got an 87 turbo and trying to figure it out thanks for looking

Tan color is low Impedance.(86-87 Turbo)
the 88 Turbo injectors are purple and are HI impedance.
........and it IS in the FAQ's!
The 2 common TII Ecu's used on the S4 TII are N332 and N333 and like to See HI impedance.
If the Injectors are LO impedance then there is a Resistor pack that is used.The resistor is factory Wired to be placed in series with the LO impedance Injector and makes it "appear" HI so it matches with what the ECU is looking for Impedance Wise.
IF NO resistors are used then the Injectors are HI impedance injectors.
You could always take a connector off of one of the Injectors and place an OHM meter on the injector.If it is about 3 ohms then it is LO Impedance.
