New injector wiring question.
New injector wiring question. In the picture below, which method do you think would be best for wiring in my new injectors? Each have their pros and cons. I am going to use 39# Mustang Cobra injectors, which use USCAR style connectors, not the standard jettronics connectors that our injectors use.
In the pic, The black square represents the stock LS1 injector connector, the blue square is the new jetronic connector. The red and black lines are the + and - leads.

Diagram A:
basically cuts the OEM connector off, and solders the new connector on.
Pro: Easiest job to perform. No spare connector to short out. Neatest install.
Con: If I decide to switch back, I must kep the originals and them cut the new of and solder old ones on.
Diagram B:Pro: Easiest job to perform. No spare connector to short out. Neatest install.

Solder the two connectors in parallel.
Pro: Easiest to perform. No additional work if I go back to OEM style injectors.
Con: possible to get the unused terminals dirty so they are unusable if I go back? May look Messier having extra connectors if they are not tucked away. Possible to have an unused connector short out against something?
Diagram C:Pro: Easiest to perform. No additional work if I go back to OEM style injectors.

basically cuts the OEM connector off, and solders a new plug on to teh fuel injector harness. A mating connector is soldered on to each pigtail.
Pro: Easiest swap between teh different style injectors. Neat install. No possibility of shorting an extra/ unused lead.
Con: More connection = more possibility of connection problems (bad contacts) later on. a slightly higher cost (not much really).

I would go with eaither (A) or (C). If you plan on swaping back and forth (C) is deffently the way to go... (B) would be out of the question.
Another option that you could do would to be find a spare harness and splice it at the rear with one connector, per side. Then you would have a harness for each set of injectors, with less connectors and plugs to worry about..
