I'm putting ITB's on a 12a rotary but need to know a couple of things. Now i know that the s4 had low impedance injectors, while the s5 had high impedance injectors. The connection clips the same on them? By connection clips i mean the plastic clip that hold the electrical connections. I'm buying the s5 type injectors so I just need to know what clips to get, also if you know of any place that you can get them new that would be great. Thanks

 

the s5 has oval injector clips vs. the square s4's

 

Actually 86-87.5 cars had low impedance injectors, and 87.5-91 had high impedance injectors.

The injector supplier should be able to provide you with matching pigtails for whatever injectors you buy.

 

Hey,

Thanks for letting me the difference. The guy that is selling them on ebay is saying that they are a direct swap in so no piggy tail included with them
