I just changed the spark plugs and oil on my 88 tII. I went for a drive and the oil pressure gauge no longer works. I am assuming that I damaged the wire or something because it worked before hand. However, I am not sure where the oil pressure sender is located. So... where is the sensor located so I track down the problem?

 

Under the oil filter.

 

nevermind, Im just a dummy. I figured it out.
