I used the 240 single wire sender for my temp gauge on LS swap since I could chuck it in the lathe and turn it down. Yellow/ white wire to it. Now the two gauge wants to peg every time the dash lights are on or jump up and down with turn signals. The yellow/black wire that I thought supplied ground for the sender I have left alone. Should that have been grounded maybe?
Also since LS runs hotter than redblock is there a way to add a resistor in-line to make 200 a midway point?
TIA
