The HLRPT is that red plastic boss mounted on the left side unibody 
frame runner alongside the battery box with a hex screw in it to 
secure a couple of wire lugs feeding primary 12v to the car's 
accessories.   It works well when it's ok, and is the bane of late 
'Vair owners everywhere when it does not work well, causing outages 
of everything electrical intermittently on occasion when it's been 
subjected to corrosive elements like battery acid which is not 
uncommon considering where the HLRPT is located.    A dose of 
penetrant now and again will help keep the corrosion at bay.


And it WILL work well for decades if it's clean and non-bathed in 
battery acid spatter.    A quick visual inspection is usually 
sufficient to determine if it's causing trouble.    If suspicious, 
you can bypass it by simply splicing the wiring and forgetting about 
it altogether, or you can clean it or replace it.
