stangeba Posted February 18, 2022 Share Posted February 18, 2022 I hope this may help with a few of your questions and perhaps even bring up a few new ones. I replaced the heater core on my 71 NON A/C Monte. I took many pictures and have shown them here in the past. I always refer to it as the snowball effect. https://1971montecarlo.wordpress.com/1971-monte-carlo-no-a-c-heater-core-replacement-pics/ Quote Link to comment Share on other sites More sharing options...
TeeJeep Posted February 18, 2022 Author Share Posted February 18, 2022 HI Bruce! Thanks for the response; I'm looking more for the specific wires to run/chase. The old harness has a bunch that were clipped; need to figure out which ones go to the 3 prong resistor. After that i should be good to go.

Scott S. Posted February 18, 2022 Share Posted February 18, 2022 Rob Peters posted several diagrams under "70 Monte Carlo wiring diagrams"..... Might have what you're looking for. Quote Link to comment Share on other sites More sharing options...
