Re: Roof Deuce Restoration
 

Marlin,

After reviewing my '70 Chassis Assembly Manual, I realize I need a "water temperature switch" to complete my TCS system. I thot the extra wire/connector in my Nova wire harness on the passenger side of the engine bay was for the factory temperature idiot lite (or gauge as appropriate) in the cockpit (I am runnig aftermarket vintage SW gauges including a water temp gauge). It is a green wire with the "L" shaped/ 2-prong connector. I need a source for the Temp Sending Unit that it correct for this application . I believe the sending unit goes on the pass. side of the block between the two rear most spark plugs (using Charley's '70 Z28 website as a reference).

Thanks,

One word.. Awesome! https://www.yenko.net/ubbthreads/imag...ns/worship.gif

Re: Roof Deuce Restoration
 

You do indeed need a two pronged temp unit, one prong for the idiot light the other for the TCS system. This unit is installed in the driver's side head, and on cars equipped with gauges the temp sending unit is installed in the passenger side head. The two pronged unit is still available from GM I believe, somebody has the part number....

Marlin,

There is only one (green) wire going to the 2-spaded connector for this temperature SWITCH (in retrospect, I do not think it is a sender, but rather a switch). My understanding is that there is a jumper wire between the two female connections of the harness and that once the temp gets to a prescribed level the connection is completed and sends a signal to the TCS switch. Chuck Sharin found this thread over at NastyZ28.

Misc pics of Jack Seymour Hugger Orange Survivor......

A couple of pics showing SINGLE green wire going to the two pronged TCS temp sender in right head.

On the Z-28 with gauges the drivers/left head has water temp gauge sender.......

Hope Im correct here......

Good info Chuck. Now of course I have to ask the Deuce experts if the various clips in the photos above were also used on Deuces. https://www.yenko.net/ubbthreads/imag...ins/tongue.gif

Re: Roof Deuce Restoration
 

Recheck the pics I sent you of the TCS on the gutter. If you notice, the green wire is wadded up, rerouted through the gutter a ways, then junctions up to another single green wire that goes to the drivers side head if, as Marlin said, you have the idiot light setup. The car did have that setup from new, but Earl changed that as thats where the sending unit is now for the SW gauges. There should be a plug on the pass side that will need to be replaced with a TCS sending unit, and connected to the green wire that is supplied with the new harness. It is only for the TCS, not the idiot light.
In the day, we didn't bother messing with reconnecting the TCS after putting in the gauges. Damn thing kept the secondaries from opening as quick as we wanted. Smog stuff took horsepower. It needed to leave. https://www.yenko.net/ubbthreads/imag...ins/3gears.gif

Gotcha Schonye. I see now that this is the wire clip for the TCS solenoid switch harness. Thanks.

Sam,
The two bladed switch is available from ground up..

The correct temp sending unit with the threaded stud is from www.lectriclimited.com

Hope this helps and good luck.

Re: Roof Deuce Restoration
 

The two blade plug could indeed have a loop connection, haven't looked at it in a few years https://www.yenko.net/ubbthreads/imag...ns/naughty.gif Either way, ya gotta get the sending unit with the two spades! I don't recall ever seeing those wire clips on any deuces b4.... Not the first time the deuce version of the CTB/CTC was different than the Z28's.
