High impedance injectors in a low impedance harness
Cut and paste from a different thread I found:
"High inpedence injectors will work even if the resistor package is still in the car. And you'll Probably never even notice it.
High impedence injectors will work in your car but you Should take the effort to cut the solenoid resistor package's harness in two. Then put the resistor package on a shelf in the garage. Take the five wires on the cut harness and splice them all together and connect its plug back into the EM harness."i
I have a high impedance 88 Vert where I need to replace the wiring harness, and the only harness I can find are low impedance types. Based on the above advise from Hailers, it looks like I'm ok to take this approach.
My questions are based on I'm not keen on cutting any wires unless absolutly necessary. So, my questions are.
What am I leaving on the table if I leave the resistor pack in?
Not doubting Hailers, but wanted to seek a second confirmation that save for dealing with the injector connectors guide pins, all I need to do is twist all the wires together at the resistor pack connector to make the low impedance harness a high impedance harness for all intents.

Leaving the resistor pack in sounds pretty stupid.
Lower voltage to the injector should mean less opening which will result in less fuel.
It is as simple as cutting the plug out and soldering the 4 injector power wires into the main 12v source.
I'll actually be doing this tonight for a person harness.
You can see the 4 brown injector side vs the one black power side.
Actually, for the electronic guys.
Do you for see any issues with soldering in two and then the other two downline? That way there isn't one huge nasty solder joint but two smaller ones.
