Hey all,
I am trying to button up all the loose ends with my EJ22 swap. This button has to do with wiring the EA cluster to the EJ Temp Sender. I tried doing a parallel resistor. Not sure if I did it correctly. I put a 270 ohm resistor where the EA gauge cluster wire meets the EJ Temp Sender wire, then connected the resistor to ground on the body. There is no change. My gauge reads way past the "H". Does the same if there isn't a resistor. I tried putting it inline, just to see what happened. The needle then wouldn't move past the bottom line. I know that it isn't overheating. It does this after a cold night, and only turning the key to the "ON" position. Fans work correctly as well. I know I need to just do an aftermarket setup, but I'm in the midst of moving from SD to CO, and I just want a little peace-of-mind-reference for the temp....
If I were to attach the resistor to the signal wire coming off of the sender (I mean attaching it within an inch or two of the actual sender), then to a ground, will that affect the signal going to the computer? Will this mess up fuel economy? Throw a CEL? Are there any pictures of what a parallel junction looks like? I am kinda guessing. I've done a few searches (more than a few), with multiple search entry options. Not trying to take up USMB's space....
Thank you for your time,
Greg
