Wrong. There is no difference between the USDM and JDM injectors nor is there any difference with those from other markets.

Yellow topped injectors are N/A from pre89 model MKIII Supras and Cressidas. Green topped are from Supras sold in '89 and thereafter. The pre89 injectors (yellow are low impedance and require the use of a resistor pack which is found on the drivers side wheel well. 89+ injectors are high impedance. The upside to having pre89 injectors is that the GTE (all years) used low impedance injectors, so, if you're going to add a turbo to your N/A and plan on keeping the N/A electronics you may drop in GTE electronics... no can do if you're 89+.

Sheesh.....



EDIT: also of note is that if your vehicle has one color and the other vehicle has the other the wire harnesses are generally NOT compatible... you'll need to swap your old harness over.
