<VV> TEMP/PRESS Light

Thanks guys for your quick responses!  So the temp switch is under the turkey roaster, or on top?  I couldn't for the life of me find a wire and switch for that sender, but I'll look again where you suggested.

I already took the pressure sender off and adapted a tee for my temp and pressure gauges.  In fact, Clark's description of the plumbing necessary to tee the two oil gagues (temp and pressure) as well as put the stock sender back online, was very vague and not at all accurate (which the tech admitted on the phone when I called).

I was able to install all 3 where the original sender went.  And the stock sender worked, until I futzed around with the instrucment cluster, repairing some burnt out dash lights and other wiring problems (all fixed under there now).

The key when mounting any temp sender, whether gauge or switch, is to keep the sender as CLOSE to the block as possible.  Clark's diagram shows the temp sender mounted way on top of a 3" brass nipple.  That far away, the oil acutally cools off before it reaches the sender and gives a false "low" temperature reading.  My design puts both the stock switch and gauge sender at the base of the engine mounting, and the pressure sender higher up (where it will register regardless of how close/far it is from the base).

While I was under the dash, I also took the liberty of making a "column shifter" for the Powerglide control, which is MUCh more convenient to use and looks nice, and is so simple that it's just a replacement for the original knob, and the stock shifting mechanism isn't even touched.  I'll try to get some pics online for this adaptation, it uses a column lever from any stock column shift GM car (my fav is the early 70s full size Chevy), a couple of "sweat in" copper plumbing parts (available in any hardware store) and solder with epoxy to put the whole thing together.

Thanks again everyone!...Bill
