Ok I have a 91 Mustang I'm using an F body cluster in. I got most the wiring hooked up but I'm not understanding how the gauge is going to see oil pressure.
The Truck Harness Says it is
.5 Referance
Low Referance
This is the Truck Sender

So The Way I have it hooked up is Pin 63 BLK Circuit 2755 Here
![](http://i178.photobucket.com/albums/w253/Big91RustyBucket/1991%20Notch%20Project/104093469.gif)
Then Pin 7 Circuit 2705 .5 Referance as the PCM Pinout says.
I ran oil Pressure output to the gauge , and to the PCM Pin.
This is the F Body Cluster Side

The F body Sender Uses 1 Wire or so it looks.

Am I Missing something here or what. BC the gauges stays at 80 it never seems to move therfore making me think it isn't right.
Also F body uses Serial Data , so I hooked the second Serial Data Pin to it. The First serial Data pin is used for the OBD Port... Please somebody Help...

Well when using hptuners I'd like to see oil pressure. I guess if I gotta deal with it I can. I'd just like to have it work. Also what will I need to do to turn off the security light and abs light and airbag light?

As far as the lights, if you don't hook them up they shouldn't light.
IIRC the security light has wire going to it to activate it and the other get their signal from the class 2 data buss, so if you have no ABS or Airbag modules they shouldn't come on

The sensor is metric, I'm not sure of the size, you could either put a T and mount 2 sensors of put a fitting in the plate on the oil pan above the filter, where some guys tap their oil feed for their turbos

I reconfigured the 99 F body gauges in my conversion using the same 99 for all wiring (PCM, relays, etc). The voltmeter and oil pressure work but I don't appear to have the data signal for the other gauges. I have continuity between the pcm conn and the cluster plug. What is the purpose of cluster term # A-13? My dash lights work through #B-9. Do I need both? I also did not use #B-5 (starter relay voltage). What is the purpose of that term. Any input appreciated.
