How Do You Convert from 4 prong resistor to 2 prong
What this amounts to:
The two terminal and "1/2" the 4 terminal works just like any old coil resistor. That is, one side is fed power from the key, the other side goes to coil
This of course is what you keep
The 4 terminal had an additional resistor fed by the key, which led off to one terminal of the ECU. This is now not used.
So all you need to do is unhook the resistor, unhook the ECU, and do some probing
First, with the above all unhooked, turn the key to "run" and find the two plugs with power. These maybe and probably are jumpered across. One of those goes to your new resistor.
Now hook your meter to coil+ and probe the remaining two resistor plugs to find out which one this is. The color should match.
The other two you can cut off the ends and tape, tuck away, etc
Do not go by the colors in the diagram below. What you are "leaving in place" electrically is the right hand half of the resistor. The bottom blue jumper over to the left bottom, and the upper left wire going to the ECU is what you are getting rid of.
