Title: 85 - 87 vs 88 Oil Pressure Sending Unit
Post by: Donster on January 16, 2019, 04:00:24 pm: As to my question in another thread about an unknown part, things have become a bit more clear now.
And I must say, the PO is starting to P me O!
He obviously replaced the original 88 OPS with an 85-87 OPS, which has a different connector. He cut the original connector off and just crimped on standard connectors. He also only had one wire connected to the OPS, the other 2 were just dangling there.
While I still have the original connector, I still would need the correct wires/colors and to which terminal they connect. Can't find wiring colors in the 88 SM, but I also need the wire colors for the 85-87 connections.Can somebody provide?
Thanks.

Post by: Donster on June 08, 2019, 10:00:34 am: OK, new (88) OPS has arrived. The old one was making the gauge bounce all over the place - full spectrum.Installed the new one today, no oil light and the gauge goes all the way past 80 to full.
I am having way too many electrical problems with this car!

My Duke seems to run higher "hot" oil pressure than any of my V6s ever did. 55-60 lbs at idle. At least according to the gauge.
