HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

Ive "stuck" this topic to the top of "electrical mods" so that people can find it easily and hopefully post additional notes and such. Cool

Since I am running a separate fuel relay for my ecu and my car runs, I can use this pins, correct:

#6- G on oil pressure sender
#9-WK on oil pressure sender
#8- G on temp sender
#10- W on temp sender

That should be everything I need for the stock gauges.

Question, I bought the correct sensor for my lt1 that has the 3/8 npt thread and the same resistance vs temp curve as the stock 944 sensor. I wired the single wire into the blue and yellow wire, pin 8 on the female side of the 14 pin body connector. I still dont have a working temp gauge. I'm not sure what it wrong. Everything else appears to work except that my oil pressure gauge stays pegged, and i believe that is because I am using the stock GM sender which has the wrong resistance; and the PO may have wired it wrong as I just recently inherited the car.

try grounding out that wire, the temp gauge should move to the top. if it does then you may have too much thread sealer on the sensor, preventing it from grounding. if it doesnt move up you have an issue elsewhere, bad wiring in the car or the gauge just doesnt work.

the stock gm oil pressure sender will be causing the oil gauge problems, you need to run the porsche sender.

14 Pin Connector - Check Please - Page 2 Empty Clarification on temperature sensor for gauge

Post  gwistrup Sun Feb 02, 2020 9:27 am

After reading through this thread and looking at the "Manual". It says that one wire is used for the temperature gauge and another is used for the idiot light. The water temperature sensor in the cylinder head has one terminal on it. Are both wires connected to the single terminal on the sensor?

You need to use the Porsche sensor with 2 pins to make the temp gauge work properly. You can tap the hole in the head for the sensor. There is an adapter made for it, but it pulls the sensor out of the coolant flow, which can cause the gauge to read low. You can also drill and tap a hole in the top of the water pump and install the sensor there.

14 Pin Connector - Check Please - Page 2 Empty Temperature sensor

Post  gwistrup Thu Feb 06, 2020 7:11 am

So is the one wire sensor I purchased from TPC that is installed in the rear of the right cylinder head used for the temperature light? Is the two wire Porsche sensor drilled and tapped into the boss on the water pump facing up where the radiator hose points forward? Is there enough room to safely clear the throttle cable? Thank you for the help. Gil

The one wire sensor TPC sells is for the gauge only, not the light. TPC sells that sensor because there is no modification required to fit the LS engine. I have a tap that I use to re-tap the cylinder head for the Porsche sensor. The flat spot on top of the water pump can also be used for the sensor. It clears everything. My personal preference though is in the cylinder head.
