Question about fuel injectors.

[DallasN2O]

I have a broken plug on my number 4 fuel injector. Can I get a plug from a N/T car or is it a different plug on the N/T injectors? It's where the pigtail plugs into the injector. Any help w/ partnumbers or what I need to order will be appreciated.

In theory the plugs have different keys so that you don't plug the wrong impedance injector into the car but in practice I've never heard of anybody having a problem with keying when turboing an NA so you should be able to use one.

Several places sell replacement connectors. If you don't mind getting 8 of them Summit sells the MSD replacement connectors the cheapest. These are the 2G style connectors that don't require you to fiddle with the spring lock to release them. I think MachV sells them individually.

old thread...

I bought a set of new pigtails. I know the polarity is important.. which way should the wires go? Dark wire toward driver side?

The simple answer is look to see which way it was and match that. Hold a old connector up to the injector and see which wires went where. The manual shows pin 1 as the positive terminal (the black with colored stripe) but I can't tell you when looking at the injector which pin is which.
