There isn't much wiring to change to use a later cluster in an 85. If
you get the speedo with it then the oil pressure warning board should be
inside. No need to ground anything to defeat the high rpm pressure
alarm, just push a pin aside, details if you need them. If the speedo is
missing or the oil board is missing from it, a simple resistor can be
inserted into some holes in the blue foil to convert the 86+ cluster to
the 80-85 oil system, details if you need them.

It doesn't sound to hard - figure out the wiring change for the plug and ground the second oil sensor seems to be all that's needed.
