A/C question: jump pressure switch
Happy Memorial Day! Wrenching on wife's van, no time to search. 2006 Mega Cab equal pressures on A/C (~100psi high and low). Question is how to "jump"/bypass pressure switch to put in R134a. Have manual, am I jumping the 5V output of the TIPM to the the "signal" or is it looking for ground? Thank you for looking/helping!
