oleskool Posted June 1, 2023 Share Posted June 1, 2023 Does anyone know what this wire is for under the dash of my 89’ 4.0? It appears to be spliced and poorly soldered to something else in the harness. Trying to figure out what it is before I start messing with it. Appears to be a fairly heavy gauge which makes this even more concerning 😂 Link to comment Share on other sites More sharing options...
Ωhm Posted June 1, 2023 Share Posted June 1, 2023 If it a factory wire and if it could have been VIO/YEL at one time, it the Blower Motor Feed for the AC or Heater control unit. Link to comment Share on other sites More sharing options...
