I just swapped my cloth power seats for leathr power and heated seat but I was wondering if anyone knows how to hook up the heated parts. I have the other harness but I am not going through th hassle or replacing the whole harness. Also my mirrors are now heated and self dimming but same problem as the seats wiring. I have looked for a wiring diagram but have had no luck. The seats and mirrors came out of a 98 Yukon. On another note I swapped out front and rear axles of the GMC to my burb and fuel economy sucks now. I had to change out due to shredding the ring gear. To much power from the new HT383E only good thing is that with the axle swap my speedometer is almost perfect with the over sized tires and rims but lost alot of low end grunt too.
