I have just installed newer superduty seats in my 99. I'm trying to wire the seat heaters and am wondering if the upper and lower heaters should be wired in series or parallel? I guess they would be hotter if wired in parallel, maybe too hot?
No No, I believe you! Was just thinking that they would be slower to warm up that way and not as hot, but I will wire them in series for sure. I'm not too sure what year the seats are, I picked them up from a leather shop that was using them as a display. Thanks for the reply!
