[urq] Oil temperature sender location

[Louis-Alain_Richard at computerhorizons.com]

Hi there,

I want to install an oil temp sender (from a 86 4kcsq) on my car, and I 
read somewhere that it can be installed in 2 places : to replace the oil 
pan drain plug or on the oil pump itself.
Which is the best spot ? 
Is there any no-no I should know before playing with the oil circuitry ?

TIA,
Louis-Alain
