hi, checking problems with my injectors I realize that the ohms are different in the injector than the pigtail. This is normal?

i.e. injector alone = 12.8ohms

injector + pigtail = 56.6ohms

injector + stock plug without blue clip = 12.8ohms

This pigtails have resistance in the red wire:

1-004
2-031
3-007
4-017

This are obd2 to ev1 conversion harness.

 

pigtail have the aluminum wiring or copper? same gauge?

 

Yes, copper wire. Nickel connectors not know if aluminum or metal.

Same gauge as the injector plugs.

They coming with my Precision injectors like "buy gift". Not have any brand.
