Fan of this forum for the past 6 months, just bought a 97 wrangler, mostly stock at the moment. Replaced original shocks (inset big hammer here) rotors, calipers & Pads, park brake cables. Ordered tie rod, track bar, ball joints and on & on. I do have one stumper. No heater blower on & tan wire. Have chased wiring & continuity and all seems okay with the exception of the tan & brown mystery. Can anyone provide a diagram that is color coded? Any idea where the power to the 3 positions other than high, comes into the switch from? Any suggestions would be appreciated. Seems the last owner wired in an aftermarket cruise control... I'm pretty sure he wasn't an electrician.
