getting rid of the resistor box, and using OBD1 injectors

hello . i couldnt find a post on it so i figured i would share .
i have a wagon with a B16B out of a 97CTR. and well back-dating is easy . and just like the accords,preludes and obdo mpfi civic/teg they all use a resistor box due to low impedance injectors
well now im using an obd1 injector and clip on my harness with an obd0 ecu . its very simple and easy to do
you can do this one of 2 ways
option "a" cut the harness side of the resistor plug and solder them together and then cut the injector clips off and solder the obd1 injector clips on and then you put in the obd1 injectors and tighten it all back up and your done ...
option "b" you can cut the resistor box side on the other side of the plug . keeping the harness intact .solder all 5 wires together heat shrink to keep moister out and plug back on to harness . make a jumper to go from the injector clips to make it go from obd0 to obd1 . . pop in your obd1 injectors and clip on the jumper adapters .
as most of us know obd1 style injectors are better and easier to find upgrades for . it is a great option and upgrade . this will also work if you are using an obd0 to obd1 jumper harness as well . and for those who have a dpfi to mpfi jumper harness this will work as well with any any all combinations .

The reverse can also be done, i.e. obd0 injectors with a resistor box on an obd1 setup.
Obviously there's nothing to be gained from doing this, but say you're converting to obd1- that's one less thing that has to be changed.
When we converted lil'ghost's b16a to obd1, for example, we didn't change injectors. It runs with no issues.
this is mainly for people who want to go bigger injectors . there is more out ther for obd1 high impedance.
