just finishing off the 3.1, judging from the above link, this would be an oil temp gauge...
The 3.1 doesn't have that sensor... just a bolt to fill it in... and the other block is gone so will need to find another.
thnks for help.
The 3.1 just has that sensor in a different location. My 3.1 is the same way. It is the coolant temp gauge sender, on that engine, it screws into a hole in the heads on the oposite corner: the firewall/water pump corner. Over the summer when installing my 3.1L, I had to modify the wiring harnes and the coolant crossover pipe so that the sensor could be plugged in. I've been meaning to take a picture of that bolt near the tach filter and see if anyone knows how to remove it and plug up the other hole, so I could relocate the temp gauge sender in the proper location.
If you need any further clarification or help on this, just let me know via PM or email.
PS- the second picture is the tach filter, it bolts on right underneeth the ignition coil. I have a feeling jazzman or someone else would have a picture of how it's supposed to be hooked up. If you can't find one, I'll look around for something to help you out.

Both of the heads have the same drilled and tapped hole in the same corner, one head gets a pipe plug and the other head gets the sender. You can just swap the sender and plug and not have to modify the harness. The tach filter mounting tab goes under one of the coil bracket mounting bolts into the head.

This may be a stupid question, but how do you remove the plug? It has a squarish indentation on it that is just barely too large for a 3/8" ratchet extension bar to engage. Is there a special tool needed to remove it?
