Is there a difference between the wiring harness from 42lb injectors to 60lb injectors?

 

Yes.

 

whats the difference?

 

If im not mistaken, the 42's use the stock harness.

 

^^^ Spot on..

Although, if you did buy a new harness with your 42s, im pretty sure they would work.

 

I thought the GM kit came with a wiring harness? According to ZZP its because the stock size only uses 18 guage wire.

 

EV1 plug Vs EV6 plug.

foolish human.

 

thanks B

 

GM kit does not come with wiring harness.

 

yea yea.

 

2.0 SS Cobalt uses a Delphi connector on the injector. The GM stage 2 kits include ~40# injectors that use this same plug.

Most aftermarket harnesses convert to EV1 or Bosch connectors. These injectors are available in all sizes.

The 2.4 liter uses an EV6 connector/injector. You can get 60# injectors in this style. ZZP also carries an EV6 harness for the 2.0 but we normally include an EV1 harness.

Easyperformance makes our harness and they claim that larger gauge wire is equal to OEM and better than other aftermarket harnesses. I've never noticed a difference.
