I've heard that the stock harness for a 2.4 will also work for the 42's but i cannot confirm this.

If you go with aftermarket 42's or 60's you'll need a bosch style injector clips. You'll have to cut and splice them.

i see, thanks for clearing that up. now when you buy aftermarket injectors they come with the clips correct, or do they have to be purchased separately and if so where are they available?
