i'm trying to install an after market water temp sensor, i've read some really interesting ways to do this but what is the easiest?

my friend was telling me about using the stock one (next to the oil filter) running a wire from there, along the wire harness and to the Aftermarket unit, does this work?

any ideas?

 

your s5? if you dont mind the stock temp on the cluster not reading then by all mean's use that location. on the 87 you can just drill and tap the filler neck since its aluminum.

:AA:

 

mines plastic... atleast it looks plastic. and how would i go about doing this?

 

I was thinking of tapping the filler neck but was then told that I should find somewhere below the T-Stat.

I did what NZConvertible did as it is the right way to install the sender.

 

yea i found that one, it confused me thus me creating this one

 

Does your car have AC and PS?

 

yes it does

 

Nevermind then, sorry.

 

Ha!!!!!!!!

 

i put mine on my water pump right by where the stock sensor is on this flat spot
to do this you MUST take the pump off though

 

pic?

 

i'll see about taking one and PMing you it tommorow night

 

This is actually well covered in the FAQ. It's a common question.
