Congrats. Now where you able to do it with your '97 cluster, or did you have to modify the other one you had?
I think he is using a 92-96 oil pressure GAUGE, inside his 97 cluster shell, with the new sending unit (and no jumpers used)
The 97+ clusters do not have the external 20ohm resistor, it is integral to the gauge. So, by using a -96 gauge inside his 97 cluster there is no resistor being used, which means it will read like a functional pressure gauge provided you use the correct sender.
