1971 Stepside LS Build

[derotoreut]

TA_C10: I have been following your build and read through what you were planning with the 3-relays, diodes and resistors. You really put a great deal of work into it, and I applaud your efforts. Honestly it sounded good, but I was not planning to go that way because when Tilden built my harness and programmed my PCM, they used only the 2-relay method for fan control. They already wired in two relays and installed them in a weatherproof box as part of my harness. My plan (which may still happen) was to tap into the trigger from one of the fans, and tie that into the trinary switch. This was the recommendation by my harness builder (Tilden). However, if it is easier and more effective to go the transducer route, I will consider it. In order for me to do it, I think I would buy the drier already set up with the transducer and binary switch since there is no good location for me to install the transducer. Plus I'm using Vintage Air's EZ-Clip system for hose installation. My harness has already been programmed by Tilden, so that would mean I'd have to have it redone? Great info going on here. Sorry Stepside if we've hijacked your build thread for this.
