Thanks for info, that hadn't even entered my mind. I have a kenlowe fan and its thermo controlling unit ( for lack of a better discription) so was going to wire the pos feed to an on off switch. Would running a wire between the terminals to a warning light still work? And why wouldn't the warning light illuminate when switch is on? Path of least resistance? Maybe even connect this pos power lead to a VSS so it only comes on when the engine is running and not on the key. Cheers

Hi gents, interesting reading. Slightly off topic but......I've been scratching my head a lot on how to wire up a warning light when I switch off the electric cooling fans ( for deep river crossings.....V8) I have removed original engine driven fan. Then was reading through this post and a very small light came on..........could I use a VSS to switch on the warning light or is the a much better cheaper way? I probably have a couple of them sitting around as It now has a soft top, no rear window heater and a broken disco in my yard. Any advice might stop my scratch. Thanks.
