Does anyone know how to tell the difference between an 87 tii and an 88 Tii harness? I am getting an 88 Tii harness and need to know about the low and high impendence injectors.

 

I was under the impression that they are the same actually. Didnt change until 89.



Could someone confirm if this is true or not?

 

I found out something about the 87.5 had high impendence and they just carried them over or something.

 

86-87.5 cars have a resistor pack under the airbox, and low impedance injectors, the 87.5-88 cars have no resistor and high impedance injectors.



they can be interchanged, but you need to make sure the ecu sees the right amount of resistance
