When I first put an AAZ in my van, I accidentally connected the coolant temp wire to a sender on the oil filter mount (shows what I knew!). The mount has two senders -- one apparently identical to the coolant temp sender on the outlet pipe on the head. I assume that the other is an oil pressure sender?
My temp gauge appeared to work okay, though I noticed that the temp needle moved a lot more than on the 1.6! It's fortunate for me that it was still giving a meaningful reading -- during a long trip I sprung a leak on the highway and overheated. (The leak was from a pinhole on one of the stock metal pipes, which had rusted from the inside. Of course it was leaking from above the fuel tank, which meant for a very long day hacking together a repair in a parking lot!)
Anyway, I don't have an oil cooler yet, and I'd like to see my oil temps. Is there an aftermarket gauge that will correctly read the signal from the stock sender?
Also, am I right that the other sender on the filter mount is for pressure? I have a currently unused VDO gauge (

Any chance that I could get a usable signal from the stock sender (supposing that's what it is)?
